US investment bank Lehman Brothers has joined the UK pensions buyout fray, actively pitching for at least one recent deal as more and more UK companies seek to offload their pension liabilities.

Alan Rubenstein, head of the firm's European pensions advisory group, said: "Lehman Brothers is active in helping clients look at different ways of managing their pensions risks - including removing these from the balance sheet entirely if appropriate." He declined to comment further.
