Within the last few minutes, a statement has been released by Channel 4 to confirm that Mr Tumble has sensationally QUIT the BBC in a £10m deal to present the Great British Bake Off when it begins on Channel 4 in 2018.

His first publicity photo for his new role can be seen above.

According to his management team at Special Talent Inc, he will complete his contractual obligations for another 50 episodes of his various CBeebies TV shows before making the move.

The statement also included comments from Mr Tumble himself, and he said: ‘I would like to thank the BBC for all of the support that they have given me over the last few years, but this was an opportunity that I couldn’t turn down.’

‘Mel and Sue have left some pretty big shoes to fill, but I am taking on the role as a single presenter as the network executives have assured me that I will be allowed to continue teaching the audience all about Makaton.

I am also very excited about the introduction of a ‘secret ingredient’ in every episode that will be pulled out of my spotty bag.’

However, in a late development it has emerged that a legal row could be brewing over the copyright of Mr Tumble’s name and clothing.

According to a number of TV industry experts, Channel 4 may be forced to drop the ‘Mr Tumble’ name to avoid a five-year ‘no broadcast upon exit’ clause.

A source at Channel 4 confirmed that to begin on time in 2018 the show may have to refer to him as ‘The Pantry Clown’ or ‘Makaton Micky.’

There is also a rumour that Mr Tumble may have been pushed into this move by the BBC’s decision to temporarily suspend him over an expired CRB check earlier in 2016.
