Marks & Spencer’s mid-season Sale will begin tomorrow, when prices on selected lines will be cut by as much as 50 per cent.

The retailer said the event is always scheduled dependent upon the timing of Easter and this year’s timing is no different.

Last year the mid-season Sale began on March 3, because Easter fell earlier. Two years ago it started on March 20.

Marks & Spencer’s recent performance will come under close City scrutiny next week, when the retailer issues its fourth-quarter update.
