LONDON (Reuters) - Barclays reported its first quarter profit fell 12% on Thursday, as it showed early signs of the difficulties it will face in delivering on its first strategic revamp in a decade.

The British bank reported pretax profit for the January-March period of 2.277 billion pounds ($2.84 billion), down from 2.6 billion pounds a year ago and in line with the 2.2 billion pounds average of analysts' forecasts as compiled by the bank.
