T&S Stores has left the Association of Convenience Stores (ACS) after admitting that its beliefs are out of kilter with those of the organisation.
The Tesco-owned retailer said it can no longer remain a member of the ACS, which wants the OFT to change its definition of the UK grocery market (Retail Week last week).
The existing definition has been favourable to Tesco, enabling the grocer to push into the convenience market unchallenged.
Tesco chief executive officer for c-stores Colin Holmes said: 'Consolidation in the sector will continue, re-shaping this market in coming years. We are unable to support ACS's strong stance on this issue.'
