Britain's top share index fell back after a volatile session on Wednesday, swinging back from early strong gains in low volumes, with banks seeing gains eroded, although Lloyds Banking Group was boosted by a broker double upgrade.
At the close, the FTSE 100 index was down 29.86 points, or 0.6 percent at 5,389.74, reversing a chunk of Tuesday's 1.0 percent advance.
The index ended not far from the session low of 5,371.65 having hit a peak for the day at 5,479.19, with volumes around 85 percent of the 90-day moving average.

News that lenders snapped up the European Central Bank's offer of three-year loans on Wednesday, taking nearly 490 billion euros (409.71 billion pounds), well above the 310 billion euros forecast in a Reuters poll, had an initial positive reaction.
It seems the sheer amount of money demanded by banks has shocked investors. Banks can borrow from the ECB at 1 percent and then buy various Government debt ranging from 3 percent-6 percent yields, so no wonder so much money has been taken up by this move from the ECB, said Simon Furlong, Trader at Spreadex.
However the stakes are high. If European countries do start to default then Europe could see an unprecedented financial meltdown, Furlong added.

The euphoria has proved to be short-lived ... We are however avoiding any signs of a rampant sell-off for now and the expectation is that volumes will slow sharply over the next day and a half, said Yusuf Heusen, Sales Trader at IG Index.
Volatility is likely to remain though, and with shares relatively depressed, some pre-Christmas bargain hunting wouldn't cause much surprise, Heusen added.
