Courtesy of the Everyman: Famous Soviet skater in bar accompanied by girl (7). I have R_D_I_A (where the last A might be dubious). Bloody girls' names again. There are, after all, only about three of them...
Yeah rab - we thought it was RODNINA - the first name of a well-known Soviet ice dancer [maybe figure skater] - I think her surname was Tereskova [Sp?]. As you can see, the breakdown of the clue is fairly straightforward.
