Property firms climbed in a weaker London on Friday, with British Land one of the strongest performers after a news report said that it could be a takeover target.

British Land shares rose 4.3% in the top London index.

The gains came after the Daily Telegraph newspaper reported that a consortium is planning to bid as much as 10 billion pounds ($16.5 billion) for the firm, which is one of Britain's biggest property developers.

The consortium is thought to include Lakshmi Mittal and the Abu Dhabi ruling family, the paper reported.

Shares were higher even after British Land said that it hasn't received interest from potential bidders, Dow Jones Newswires reported.

Other listed property firms were also higher, with Liberty International shares up 0.6% and Hammerson shares up 1.5%. Land Securities shares rose 1.2%.

The FTSE 100 index declined 0.9% to 4,714.92. Other European shares were also lower.

The U.S. consumer sentiment index unexpectedly declined in early August to 63.2 from 66.0 in July, according to media reports on Friday of the Reuters/University of Michigan index.

Shares have notched fresh 2009 highs in recent sessions, with investors increasingly optimistic that the economic backdrop is improving.

However, some of the companies that have performed well in recent sessions were lower on Friday afternoon, with miner Rio Tinto (RTP) down 2.1%.

Banks were also under pressure, with HSBC Holdings (HBC) down 3.2% and Barclays (BCS) shares down 1.2%.

Outside the top index, shares of easyJet traded down 1.9%.

Credit Suisse cut its rating on the airline, Europe's second-largest low-cost carrier, to neutral from outperform, citing the 22% increase in its share price over the past month as well as the potential pressure on near-term ticket prices.

In particular, the broker expressed concern at the company's plan to increase capacity by 10% this winter because of its potential impact on fares.
