Derwent London plc share price falls on FTSE 250

Although this figure was up from last year (loss of £606.5 million), the shares were subject to 'selling pressures' as they had more than doubled over the past year.

Derwent London, however, gave an upbeat outlook for 2010 as the value of its portfolio had stabilised with a 10 pct second half increase.

The company, which specialises in West End offices that cater for mid-market companies, said that it expected rents to start increasing again, whilst investment prospects remained limited.

The share price fell 16 pence to 1,322.00 (-1.20 pct) by 1:38pm as investors shunned further buys.
