To avoid an overlap of the shows, tomorrow night's 'Strictly Come Dancing' will start at 6.10pm ending at 7.30pm when 'The X Factor' will begin, with the BBC's new drama 'Merlin' going up against 'The X Factor' instead.
Although an overlap has been avoided this week, on the following Saturday 'Strictly Come Dancing' will run 20 minutes into 'The X Factor'. The first finishes at 8.05pm and the second starts at 7.45pm.
The second bootcamp episode of the ITV series has been moved to Sunday night at 7-8pm.
This is not the first time ITV have moved an episode of 'The X Factor' to a Sunday and is not set to cause any problems with the voting and results announcement because it is a bootcamp episode rather than a results show.
The scheduling change does however now mean that 'The X Factor' will replace the final episode of ITV1's show 'For One Night Only', which will be rescheduled at a later date.
