Just 20 per cent of the bank’s investors are believed to have backed the capital raising, as the shares have traded close to the 55p rights issue price over the past two months.

On Friday the shares closed at 54.75p.

With the rights issue out of the way, institutional investors are expected to press for Kent to resign, as soon as a replacement is found for departed chief executive Steve Crawshaw.

B&B and its investors have fallen out over a number of issues, starting with the bank denying claims it needed emergency funding in April, only to launch its rights issue a month later.

Kent’s ill-fated attempt to sell a stake in the bank to private equity group TPG in June also infuriated investors.

Over the past four months, a number of banks have had to go cap in hand to investors for extra cash to prop up their balance sheets.

HBOS staged the worst supported rights issue.

Of the £455 million B&B raised, £55million will go to its advisers UBS and Citigroup. Standard Life Investments, M&G, Insight and Legal & General Investment Management have committed to buying £179million of new B&B shares.
