Retail sales rose 0.9% in January compared to December, according to the latest figures from the Office for National Statistics (ONS).
The figure was much stronger than forecast as many economists had expected sales volumes to fall.
But some retailers say the latest figures hide deeper problems.
Sir Philip Green, owner of the Arcadia group of shops - which includes Topshop and Dorothy Perkins - says retail figures are affected by the weather.
