Vale DJ Dave Lee Travis has been charged with two counts of indecent assault, in addition to 12 charges he already faces.
The former BBC Radio 1 from Mentmore is accused of assaulting a woman aged over 16 between January 1, 1992, and December 31, 1993.
Mr Travis, 68, real name David Patrick Griffin, is due to appear at Westminster Magistrates’ Court tomorrow.
He had already been charged with 11 counts of indecent assault and one of sexual assault, which he has indicated he will plead not guilty to.
Those allegations date from 1977 to 2007 and relate to nine women aged between 15 and 29 at the time.
He expected to face trial for the initial charges from March 4, 2014.
