Tesco has acquired six former Somerfield stores from the Co-operative Group after competition authorities gave the deal their blessing.

The Office of Fair Trading said yesterday it would not be referring Tesco’s purchase of half a dozen former Somerfield outlets to the Competition Commission.

Tesco swooped to acquire the stores in the wake of the Co-op’s £1.57bn takeover of rival Somerfield last year.

The deal saw the Co-op pledge to sell off a swath of Somerfield stores in a bit to head off regulators’ concerns over competition issues.

Earlier this month Sainsbury’s snapped up two dozen stores from the Co-op for a combined £83m, in the latest deal to result from the landmark takeover.
