Independents are divided over Customs and Excise proposals to put a duty paid stamp on spirits. Association of Convenience Stores chief executive David Rae said the ACS was concerned that costs of implementing a stamp would be passed on to retailers. He said: "We urge the government to work more closely with industry to address the problem of fraud before introducing a tax stamp." But Scottish Grocers' Federation said: "The SGF is backing a UK duty paid stamp on all spirits in the fight against bootlegging. The new tobacco stamp has brought increased sales in the last six months." Scottish Spar retailer and wholesaler CJ Lang has reported tobacco sales are up 9.1% since the introduction of the UK duty paid mark. {{NEWS }}
