Shares in the UK's four biggest supermarket groups were up.
Tesco jumped over 4% early morning, while Marks & Spencer was up more than 9%.

Retailers will be helped too by the pound rallying to an 18-month high against the U.S. dollar, as the cost of importing goods and raw materials goes down.
Fashion brands also had a boost.
Shares in Associated British foods - owner of fashion retailer Primark - were up almost 6%.
Shares in Next were up 4.2%.
Brexit has weighed on Britain's property market this year.
But with a clear path in the short term, shares in Kingfisher - owner of home improvement chain B&Q - were up over 5%.
