Lehman Brothers in Britain collapsed with a mammoth £100 million black hole in its staff pension fund, it emerged last night. The deficit means that many former staff in Britain may not have their retirement promises met in full. Trustees of the fund wrote to the Pension Protection Fund (PPF), the industry lifeboat, last week seeking assistance, as The Times revealed on Saturday.

The size of the shortfall surprised experts. The £100 million deficit, confirmed last night by Pricewaterhouse-Coopers, the administrator, compares with one unconfirmed figure for total assets in the fund of only £180 million.

There could be only 50p or less in the pot for every £1 of pension promised.

The PPF is financed by all 7,800 final-salary pension schemes in Britain. The failure of Lehman to keep the pension scheme topped up means 12.5 million Britons may have to pay a higher PPF levy in future.

Under the PPF, pensions up to £28,000 are paid in full. John Ralfe, a pensions consultant, said: “One way or another, the members of Lehman’s UK pension scheme will lose out.”

Members of the scheme include 1,500 Lehman employees in London until last week, as well as 2,400 “deferred members”, former employees, who left the bank but continued to entrust the scheme with their benefits.
