Every licensed premises checked by police passed a test purchasing operation for under age drinking.

Eleven premises in Bicester, two in Yarnton and one in Kidlington refused to sell alcohol to underage customers working as part of a police operation.

Neighbourhood Special Officer for Bicester town, Pc Nicki Entwistle, who led the operation, said: "Along with the council and Pubwatch, we have been working hard to stop children getting hold of alcohol.

"In both Kidlington and Bicester, alcohol-related antisocial behaviour has been nominated as one of our policing priorities by the public.

"These results would suggest that the message is getting across to licensed premises that it is not acceptable to serve alcohol to under-18s. We would like to congratulate all those that refused our volunteers. However, they need to keep up these high standards: this is just the first of many regular operations."

Cherwell District Council's portfolio holder for Community Health and Environment, Councillor George Reynolds, said: "Partnership working between the council and the police is key to our priority of providing a safer, healthier district.

"This innovative operation has shown that we're making significant progress especially in this vital area of illegal alcohol sales. We look forward to mounting similar joint operations with the police again."

The operation took place on May 29 but police only released the results today.

Police have refused to release which pubs passed the test.
