Technology issues were among London's weakest features, with sector sentiment knocked by talk that France Telecom and Finmeccanica were having trouble placing their equity stakes of ST Microelectronics, Europe's biggest chipmaker.
The two announced this morning that they were selling up to 11% in the chipmaker through a private placement of equity and exchangeable bonds.

Telecoms issues also came under renewed pressure. ABN Amro 'reduce' advice led mmO2 down 1-3/4 to 89-1/2, while Vodafone dropped 5-1/4 to 184-3/4 as it denied a Sunday Times article claiming that it is close to agreeing a new revenue-sharing deal with Vizzavi.

Trinity Mirror, a second liner, shed 11 to 411-1/2 after warning that, on its three national titles, the outlook for advertising in December is similar to November.

This has continued into the fourth quarter, with declines of 10.1% and 20.7% in October and November respectively, said the company in a trading update covering the six months to December 30.
It was Aggreko which led the mid-cap fallers, with a drop of 47 to 353-1/2 after a cautious outlook statement and a shock resignation at the power rental group.
Aggreko - which receives over half of its revenues from the US and has contracts to provide power for next year's Salt Lake City Winter Olympic Games in Utah - warned that demand had slowed in the second half, with problems escalating following September 11.

Otherwise, technology issues continued to weigh.
