John Lewis achieved sales of over £112m in the seven days to Saturday, its third record sales week in a row.

The figure is 15.5% up on the same week last year but also beat the same week in 2007 by 11.4%. Online sales growth was more muted, up 7% on the same week last year.

Unsurprisingly outerwear sales were a standout performer in the icy conditions, while childrenswear and home technology were also strong. Food gifts, electronic games and board games were popular too.

Singer analyst Matthew McEachran described the figures as “extremely encouraging” but warned that they should not be taken as reflective of the sector as a whole, because of the strength of John Lewis’s online offer and the fact that the Oxford Street and Peter Jones branches were unaffected by snow and helped by tourist spending.
