Morrisons said on Tuesday that from March it will increase its hourly payment to 8.20 pounds from a previous minimum of 6.83 pounds.

In July the government said Britain's hourly minimum wage will rise from April next year to 7.20 pounds for those aged over 25, from 6.50 pounds now, and to about 9.35 pounds an hour by 2020.

Morrisons said more than 90,000 staff, across all age brackets, will benefit from the move, which will cost it 40 million pounds a year.

As the firm's current pay deal ends next month, staff will also receive a lump sum payment of 2 percent of salary before Christmas.

Sainsbury's, Lidl and Starbucks have all recently announced pay rises for shop floor staff.

Several firms, including clothing retailer Next, Costa Coffee and Premier Inns owner Whitbread and pub chain Wetherspoon's have all complained about the higher costs stemming from the government's wage policy.
