Marks & Spencer's recent recovery stalled in the second quarter after reporting a fall in non-food sales.

Like-for-like sales of general merchandise, which includes its clothing sales, dropped 0.4% in the 23 weeks to 27 June.

M&S described it as a "challenging" quarter, following its strongest results in four years in the first three months of the year.

Chief executive Marc Bolland said: "We continue to make progress against our key priorities. Our food business did very well in a difficult market."

Marks & Spencer said online sales were up 38.7% compared with last year, when the website was re-launched, causing a huge fall.
