A number of parents have vowed to complain to the BBC after the corporation announced that the next Mr Tumble will be played by the veteran newsreader Moira Stuart.

According to a statement that was released this afternoon, the 67 year old African Carribean TV personality is ‘the perfect choice’ for the role as it is a casting that will ‘fulfil the BBC’s current commitment to diversity and equality in everything that it does.’

It also added that ‘Stuart’s complete inability to communicate in Makaton shouldn’t detract from the fact that she will make the perfect Mr Tumble.’

Sir Nigel Broflake is the BBC’s Head of Children’s Entertainment, and he told Southend News Network that he was ‘delighted’ to be able to make the announcement.

He added: ‘For a number of years now, Justin Fletcher has made the role of Mr Tumble his own, and we are eternally grateful to him for everything that he has done.’

‘However, we have a commitment to ensure that our output reflects the general makeup of British society and those who pay for the BBC through their licence fee, and so we decided that it was time for a fresh thinking approach that would be entirely out of the box.’

The news comes on a day of huge change at the BBC, with bosses announcing just a few hours ago that Idris Elba has been cast as Hyacinth Bucket for the 2018 remake of Keeping Up Appearances.

It is thought that Elba will be free to film the new series once production is complete for his latest project playing Nigel Farage in an upcoming biopic about the ex-leader of UKIP.
