The slump in Footsie is so complete that there are no constituents whose share price has risen today. The best performer is British Land, whose share price is 0.25% lower. The rights issue announcement from National Grid has knocked its share price. The two-for-five rights issue at 335p a share will raise £3.2bn. The rights price was set at a 43.7% discount to the previous day's share price - adjusting for the previously announced 24.84p a share dividend.

They are still worried about a decline in demand for metals because of the weak global economy.
