FORMER BBC Radio 1 DJ Dave Lee Travis allegedly assaulted his youngest victim at a Showaddywaddy gig at a farm near Stroud, a court has heard.

The 15-year-old girl was allegedly assaulted at a Showaddywaddy concert at a farm in Gloucestershire on June 17, 1978, where the defendant invited her in to his trailer for a drink, London's Southwark Crown Court was told.

A concert took place on that day at Gables Farm, Old Airfield, in Moreton Valence, according to Showaddywaddy's website.

Travis, from Buckinghamshire, whose real name is David Patrick Griffin, is charged with 13 counts of indecent assault dating back to between 1976 and 2003, and one count of sexual assault in 2008.

He denies all the charges.

The trial continues.
