Tesco sales spurt puts pressure on SuperValu

Tesco saw its strongest sales growth at its Irish operations in five years in the past three months despite grocery prices continuing to fall.

Latest figures — for the 12 weeks to September 10 — from consumer insights agency Kantar Worldpanel show Irish grocery price deflation eased to 0.4% but that falling prices failed to stunt market share growth for the big players.

Tesco has a a 22% share of the Irish grocery market; just 0.1 percentage point lower than leading player SuperValu.
