The grocery giant said like-for-like sales slipped 1.5% year on year to £9.88bn in its core domestic market over the first quarter, but that it increased market share by 37bps, “outperforming on both value and volume”.

Tesco said year-on-year performance was “impacted by annualisation of lockdown last year, most notably in general merchandise, clothing and online, partially offset by inflation”.
