LONDON, Dec 29 (Reuters) - Britain's top share index was up 2.5 percent by midday on Monday, as stronger crude and metal prices lifted heavyweight commodity stocks, while banks and retailers were firmer despite a glum economic picture.

"It is the rebound of the U.S. crude that's driving the market at the moment. All eyes are on gold as well with the $900 level as the short-term resistance. At the moment, it's all about metal and oil," said David Fineberg, a senior dealer at CMC Markets.
