In London on Tuesday, the FTSE 100 lost 0.4 percent to 5,322.3 and the FTSE 250 was down 0.1 percent to 7,697.0 on a volume of 2.8 billion shares traded.

The biggest loser of the day on the FTSE 100 was Cable and Wireless, on concerns that it is paying too much for Energis, its smaller rival.

Meanwhile, elsewhere in the telecommunications sector, O2 lost 2.6 percent to 142 ¾p after it was confirmed that Deutsche Telekom and KPN would not bid for the mobile phone group. It was a surprise to some analysts that O2 was up after the announcement, as speculation on a possible merger had been driving its gains since the beginning of the year.

Logistics group Exel gained 0.9 percent to 995 ½p on rumors that a bid for the company would come soon. Gains had been higher earlier in the day, but slipped back as the talk diminished during the session UPS and Deutsche Post have both been mentioned as being interested in Exel.

Insurer Royal & Sun Alliance also benefited from rumors of a bid on the company, gaining 4 percent to 96 ½p, the best performance on the FTSE 100 on the day.
