Gary Barlow has admitted that it is "inevitable" that his former bandmate Robbie Williams will perform with Take That again.

The band's frontman made the comment during an appearance with Tory leader David Cameron at a secondary school in Cheshire. Asked if he would work with Williams again, he said, "We'll see. I think it's inevitable one day we'll get back together."

Barlow was launching a singing competition for pupils at the school called 'School Stars'.

Williams left Take That in 2005 but speculation has been rife that he will eventually return to the band.
