London's benchmark FTSE 100 index of top companies added 0.56 percent to close at 5,841.24 points even as charges against Standard Chartered bank weighed heavily on its shares.

In London, the emerging markets bank Standard Chartered topped the fallers board however after US regulators accused the lender of hiding $250 billion (201 billion euros) in transactions with Iranian banks, plunging the banking sector into fresh crisis.
The London-based lender saw its share price collapse 16.76 percent to stand at 1,223.57 pence, having been down by one quarter at one point.
New York regulators have branded Standard Chartered a "rogue institution" and threatened it with fines and the suspension of its licence.

Asian markets mostly rose in earlier trade on Tuesday amid growing hopes that the European Central Bank would soon restart its sovereign bond-buying scheme, but gains were capped by profit-taking after recent gains.
Hong Kong finished 0.37 percent higher, Shanghai increased by 0.13 percent, Sydney climbed 0.45 percent and Tokyo rose 0.88 percent, while Seoul closed flat.
