Retailers have attacked the Chancellor's decision to increase National Insurance. British Retail Consortium director general Bill Moyes said: "While we understand the rationale, the government must understand that this is a tax on jobs and will potentially reduce domestic demand." Association of Convenience Stores public affairs and commercial manager James Lowman said: "The rise in the contributions is very disappointing. In the small store sector staff employment is already high, at 9.1% of turnover. Some 60% of employees pay national insurance and this 1% increase will raise costs further." Scottish Grocers' Federation chief executive Scott Landsburgh said the rise would be a serious burden on small retailers. {{NEWS }}
