LONDON, Jan 22 (Reuters) - European shares fell on Friday to post their worst weekly fall in nearly three months, with financial stocks hit by U.S. President Barack Obama's vague proposals to curb risk-taking at banks.
The FTSEurofirst 300 <
> index of leading European shares closed down 1.1 percent at 1,024.95 points, losing for the third consecutive session.The index lost 2.6 percent for the week, its worst weekly percentage fall in nearly three months and is down 2 percent this year.
"It is all to do with the banks. The bottom line here is we have no idea how the banking plan is about to unfold, if indeed it does," said Peter Dixon, economist at Commerzbank.
"This is all at a time when markets are already fairly wobbly. The markets are always going to sell off when there is uncertainty. I think this is the story for today and will be for the next week."
Banks took the most points off the index after Obama unveiled tough new proposals on Thursday to limit risk-taking in the banking sector and restrict some of the banks' most lucrative operations. [
