Retailers came under mounting share pressure as gloomy sales figures confirmed dire conditions on Britain's high street.
Mothercare and Laura Ashley became the latest to report sales falls, prompting a second day of pain for retail shares after this week's profit warning from PC World and Currys parent, Dixons Retail.
Wine retailer Oddbins said it will go into administration after the Government's tax department refused to back a rescue deal.
The struggling off-licence hoped to restructure its debts through a company voluntary arrangement (CVA), but HM Revenue & Customs - a significant creditor - would not support the move.

Babycare chain Mothercare slumped as much as 10% after it said UK sales remained in the red - down 2.4% in its final quarter - and revealed profit margins were taking a bigger-than-expected hit as difficult conditions force it to discount stock.

The flurry of grim updates from retailers has sparked fears for the sector over the year ahead as consumers rein in spending in the face of Government cuts, tax hikes and soaring inflation.

Official figures earlier this week showed household disposable income fell for the first time in 30 years at the end of 2010 after wages failed to keep pace with inflation.
