Woolworths are to launch a closing-down sale after administrators said they had so far failed to find a buyer for the ailing retailer.

More than 200 jobs under threat at the store's branches in Chippenham, Swindon, Devizes and Marlborough as the hunt for a rescue continues.

Deloitte warned tofay that some stores could close before the end of December if no offers for the business emerged.

Woolworths has been in business for almost a century but was forced to call in administrators two weeks ago as debts and losses mounted in a worsening high street climate.

Deloitte, which has already launched a massive sale with up to 50% off toys and gifts to generate cash for creditors, had previously pledged that stores would carry on trading beyond Christmas while a rescue deal was sought.

Reorganisation services partner Neville Kahn said Deloitte was making "every effort" to convert interest in Woolworths into firm offers.

"While we are still seeking bids from interested parties, Christmas is clearly the busiest time of the year for retailers and it is prudent to do all we can to sell existing stock.

"By moving to a store closing sale and further discounting the stock, we are maximising the sales potential that this period offers."

Deloitte has already cut 450 jobs at Woolies' head office and support operations in London and Castleton, Rochdale. If stores close before the end of December, the administrator said it would consult employees to discuss the support available in the event of redundancies.

Deloitte has held talks with the likes of former Woolies chief executive Sir Geoff Mulcahy and Dragon's Den star Theo Paphitis but no deals have been struck.
