Lloyds Banking Group has topped a new list as the most complained about UK bank, according to data released by the Financial Services Authority (FSA).

The state-backed group received more than 280,000 gripes in the first half of 2010. Lloyds has claimed that it received the most complaints because it is the largest bank.

"The UK banking industry is committed to its customers and to resolving problems as quickly as possible, that is why a lot of complaints are resolved by close of business the next day," said a spokesman for the British Bankers' Association.

"It is extremely important to keep the figures published by the FSA in context: the larger the bank is the more complaints it is statistically likely to receive."
