Marks Spencer has said sales for the three months to 28 March grew 1.9%.
Closely-watched general merchandising sales, which include women’s clothing, rose 0.7% on a like-for-like basis over the quarter, its best performance in nearly four years.
Sales in food also rose by 0.7% for stores open at least a year.
However, overall international sales declined 3.8% as conflict in Ukraine continues and Russia’s economy struggles.
“We had a record Valentine’s Day and launched over 350 new products over the quarter,” said the company in a statement.
Thursday’s figures are a trading update and full profit figures for the year will be posted on 20 May, the company said.
