The head of Barclays' investment banking business, Rich Ricci, has resigned, the bank has announced.
The move follows the arrival of Barclays's new chief executive, Antony Jenkins.
The boss of the bank's wealth management business, Tom Kalaris, has also quit.
Both men played key roles under Bob Diamond, the former Barclays chief executive who left after last year's Libor rate-rigging scandal.
Mr Ricci gets a year's salary after departing, unless he lands another new job in the meantime.
Barclays declined to reveal his basic salary and pension package.
Mr Ricci, who has been with Barclays for 19 years, has often attracted controversy over his pay.
Despite waiving his bonus last year, he landed £18m from selling 5.7 million shares he gained as part of annual bonuses and incentives schemes in previous years.
He will be replaced by Eric Bommensath and Tom King, who will share the job as co-heads.
Barclays' Mr Jenkins said: "Today's changes will ensure we have the right senior team in place to deliver strategy and commitments we made on 12 February and build the 'go-to' bank."
Consumers who want to sell their houses via so-called "quick sale" companies are in danger of being misled, according to the Office of Fair Trading (OFT).
Quick house sale providers offer to buy houses in as little as seven days, but at a discount to the full market value.
The OFT is warning that homeowners may receive much less for their property than it is worth.
"Any losses could be very high," it said.
In some cases such companies agree to buy a house, but then reduce the price at the very last minute.
"Businesses offering quick house sales may provide a useful service for homeowners who need to unlock cash in a hurry," said Cavendish Elithorn of the OFT.
"However, they are often used by consumers in vulnerable situations and therefore we are concerned about the risk of consumers being misled and losing out on large sums of money," he said.
Consumers identified as particularly at risk include those selling after a relationship breakdown, or the elderly who might need the money to pay for long-term care.
False valuations
During an investigation last year, the BBC spoke to two people who were angry at the way they had been treated by quick sale companies.
• making misleading claims about a property's value
• falsely claiming to be a cash buyer
• exclusive contracts, preventing sales to other buyers
Malcolm Haywood, from Lincolnshire, wanted to sell his house quickly, and agreed to a sale price of £120,000.
But just before the deal was signed, the company involved, Gateway Homes UK, dropped the price to £80,000.
Pat Hardy, from Teesside, signed a similar deal with Tom Craven Property.
She had agreed a purchase price of £75,000, but the day before the removal men were due to arrive, they lowered the offer to £40,000.
Both companies insisted that the number of complaints amounted to less than 1% of their customers.
The OFT said practices which cause concern include unclear fee structures, reducing the price at the last minute, and wrongly claiming to be a cash buyer.
It also warned about companies making false property valuations, and tying customers into contracts which prevent them selling to other people, should alternative, and more generous offers emerge.
The OFT would now like to hear from anyone who has used a quick sale provider, whether their experience is good or bad.
Retail sales in March were 0.7% lower than in February because of bad weather, according to the Office for National Statistics (ONS).
The ONS also said retail sales volumes last month were 0.5% lower than a year earlier. The decline was in line with economists' expectations.
However, in value terms, retail sales were 0.1% higher.
Non-food sales plunged 4% in March, their largest monthly fall in more than three years.
But consumers turned to the internet in the cold weather, with "non-store" retailing seeing its biggest rise since March 2009.
"Feedback from department stores, clothing stores and household goods stores suggested that sales were dampened by the weather, as they prepared their stores for the spring season," the ONS said.
Analysts had broadly predicted the fall.
"It's obviously disappointing that it's down just under a percentage point on the month, but given that it jumped by 2% the previous month, it was always going to give back some of that prior strength," said Alan Clarke at Scotiabank.
Much of Britain's GDP is generated from consumer spending and analysts have said the retail sales figures will feed into the broader economic picture.
"I think we shouldn't get carried away and read too much gloom into this," said Brian Hilliard at Societe Generale,
"It will weaken [first-quarter] consumption numbers and that's again a disappointment which might lower people's expectations for Q1 GDP."
Meanwhile, business leaders called on the government to do more to help the High Street.
"Although it is possible that the UK economy may narrowly avoid entering a new recession, the weak economic climate means that the outlook for retailers is likely to remain challenging for some time," said John Longworth, director general of the British Chambers of Commerce.
"Against this backdrop, we urge the government to do all it can to help support enterprise and wealth creation and open up new opportunities for UK firms to exploit both at home and abroad," he added.

Some 60% to 80% of fossil fuel reserves owned by listed firms could be classed as unburnable if politicians stick to CO2 emission limits, a report warns.
The research by the London School of Economics and NGO Carbon Tracker says firms spend billions of pounds of shareholders' money on exploration.
It says 200 listed firms spent £440bn in 2012 chasing more coal, oil and gas.
It says if this continues for a decade - and if CO2 limits are achieved - they would waste over £4tn.
The research says the listed companies analysed own 762 billion tonnes of CO2 in the form of coal, oil and gas.
Many of the firms are listed in the City of London - the world's fossil fuel investment capital.
To stick to the current agreed global limit on emissions - which is sure to be breached - the firms would probably be able to emit no more than about 125-275 billion tonnes of CO2 - about a quarter of their assets.
The authors say that, even if the rules are relaxed to allow emissions to a level associated with a 3C temperature rise, there will still have to be limits on fossil fuel burning.
The carbon capture and storage technology can strip carbon from fossil fuel exhaust gases and store it in rocks, but it is unproven at scale, trials are years behind schedule and it may not work in some areas of the world.
The authors say the current fossil fuel business model assumes that there are no emissions limits.
This attitude is perhaps hardly surprising, given the mismatch between politicians' rhetoric on the need to cut emissions and the continued rise in atmospheric CO2.
Carbon Tracker has been campaigning for regulators to force firms to disclose the potential CO2 emissions embedded in their fossil fuel reserves, in order to inform potential investors.
Staff at some of the UK's biggest post offices are on strike in a dispute over shop closures, jobs and pay.
To stem £40m-a-year losses across about 370 "crown" offices, the Post Office plans to move 70 from high streets into local retailers. About six will close.
The Communication Workers Union (CWU) says hundreds of jobs will be affected.
The walk-out began at lunchtime, and the CWU has warned that there could be further strike action.
The Post Office said it had to address losses. Some 97% of the network would operate as normal, it added.
Union warning
Crown offices are branches directly managed by the company - as opposed to locally-run by sub-post offices - mainly based in High Streets.
The CWU said the offices handle about a fifth of Post Office business and 40% of financial services sales.
The union said it expected Friday's action to close offices or lead to drastically reduced services and opening times.
CWU general secretary Billy Hayes said the plans amounted to "a Post Office closure programme in a desperate attempt to slash costs to meet government funding cuts by 2015".
He said the Post Office could "talk about transformation and sustainability all it likes".
"But the reality is that these are euphemisms for closing offices, drastically altering the make-up of the Post Office network and handing the running of services over to corporations which are built around other income streams and could walk away from Post Office services."
CWU national official Andy Furey warned that the dispute could escalate.
"If the Post Office doesn't face up to the concerns of its staff and the communities it's meant to serve, then we will waste no time in issuing notice for more strike action, increasing the frequency and duration," he told the BBC.
"We've tried to keep disruption to a minimum but this is clearly not getting through to Post Office management. Full day strikes will be next on the agenda."
'Not closing'
Kevin Gilliland, network and sales director at the Post Office, said it regretted "any inconvenience that may be caused by any strike action".
The CWU's unrealistic demands are delaying our people from receiving the first payment of £1,400, which is ready to be paid into their pay packets”

"Through our critical modernisation plans we intend to turn this part of our business around and keep Post Office branches on high streets across the UK.
"We will invest £70m in 300 Crown branches and are proposing to partner 70 branches with suitable retailers."
He stressed those 70 branches "are not closing".
"Any move to a retailer's premises would offer access to the same range of Post Office products and high levels of customer service in a new modern branch."
The CWU claims staff have not had a pay rise for two years and is calling for a rise in consolidated pay.
But the Post Office said a pay offer of three cash payments was "extremely fair".
"The CWU's unrealistic demands are delaying our people from receiving the first payment of £1,400, which is ready to be paid into their pay packets," Mr Gilliland said.
