After a stunning 8.8 per cent gain in the previous session, the FTSE 100 Index was on more subdued form as traders paused for breath after a tumultuous week.

The top-flight index shifted between positive and negative territory for much of the day, before closing 75.07 points lower at 5236.26 as US markets suffered early losses.

The Dow Jones slipped almost two per cent as US Democrats unveiled a list of conditions to accompany the 700 billion US dollar (£380bn) bail-out.

In London, financial stocks lost some ground after stellar progress for most on Friday.

Buy-to-let mortgage specialist and FTSE 250 firm Bradford & Bingley lifted as much as 19 per cent on the back of reports that the Financial Services Authority has been sounding out potential buyers for the under-pressure lender, although the excitement faded later to leave the stock 1/2p higher at 281/4p.

Its bigger rivals were experiencing a mixed session, with NatWest owner Royal Bank of Scotland up 21/2p to 216p, but Barclays fell 16p to 373p. HSBC and HBoS slipped 53p to 8661/2p and 131/2p to 209p respectively.

Oil rising to more than 106 US dollars a barrel provided some positive momentum as investors pondered the wider impact of the banking rescue. BP gained 10p to 5001/4p, while Royal Dutch Shell added 41p to 1636p.

But the crude rebound caused losses for tour operator Thomas Cook, which slipped by 19p to 247p, or seven per cent.

Building materials group Wolseley was the leading blue-chip riser of the session, up 14 per cent after the firm assured that it was not in danger of breaching banking covenants. With annual results also ahead of expectations, shares rose 56p to 470p.

Yell shares were closely watched after the directories firm suspended dividend payments in order to tackle its debt mountain. Despite progress in securing additional headroom from its lenders, its shares closed 43/4p lower at 861/4p, a fall of more than five per cent.

Back in the top flight, B&Q owner Kingfisher, which is reportedly considering moving its tax base offshore to help save money, added 1/8p to 145p.

Other good performers were the heavyweight mining stocks as metals prices firmed alongside oil. Eurasian Natural Resources cheered 241/2p to 6861/2p followed by Xstrata, which added 78p to 2422p.

In the second tier, Taylor Wimpey was the top faller as a survey suggested the Government's stamp duty initiative appeared to have had little impact on the market this month. Taylor's shares were down more than 13 per cent, or 71/4p to 473/4p. Bovis Homes was also down, slipping 391/2p to stand at 480p.

The biggest Footsie risers were Wolseley up 56p at 470p, BG Group ahead 50p at 1175p, ENR up 241/2p at 6861/2p and Cairn Energy ahead 82p at 2450p.

The biggest fallers were Friends Provident off 91/8p at 947/8p, Man Group down 361/2p at 4331/2p, Prudential off 43p at 557p and Thomas Cook down 19p at 247p.
