The mortgage lenders biggest shareholders have joined forces with the six high street banks as part of a plan to raise Â£400 million to buy back shares.
Standard Life, Legal & General, Prudential and Insight will pay Â£150 million for their shares, with HSBC, Lloyds TSB, HBOS, Barclays, Abbey and NatWest owner Royal Bank of Scotland adding another Â£150.
However, according to the Daily Mail, analysts remain unconfident about the recovery of Bradford & Bingley.
Forecasts from Bradford & Bingley have been slashed by the City from 55p to 24p.
As the investors are buying shares at 55p both groups are currently down by Â£50, the newspaper suggests.
Citibank and UBS have also agreed to buy the new shares and the Financial Services Authority (FSA) is working with the parties involved to avoid a repeat of the recent Northern Rock problems.
