The start of the Guinness Six Nations is set to cause a major TV schedule shake up on BBC and ITV next Saturday (February 3) affecting popular shows including Gladiators, Ant and Dec's Limitless Win and The Masked Singer.

The Six Nations tournament kicks off on Friday (February 2) with last year's winners Ireland tacking on France (match to be aired on ITV1 at 7.15pm).

But it's the two fixtures on Saturday (February 3) that are set to cause a major change in the schedules for BBC One and ITV1 with several shows being cancelled and others to air at different times.
