A woman has gone on trial at Oxford Crown Court charged with two counts of being involved in supplying Class A drugs.

Keisha Gardener, of Northcote Avenue, Ealing, London, was arrested in October 2012 after Thames Valley Police raided three houses across Oxfordshire.

The 34-year-old denies being involved in the supply of heroin and crack cocaine worth as much as £12,000 found at a house in Sorrel Road, Oxford.

The trial continues.
