Anti-racism campaigners were up in arms Wednesday following the news that Dawn French has been chosen to play the lead role in the upcoming biopic “Fibonacci – The Diane Abbot Story”.

Anti racism groups criticised the casting of a overweight white comic actress to play the role of an overweight comic politician of colour.

“Would we see Diane or another actress of colour being cast to play the lead role in “The Dawn French Story?” Asked a spokesman.

Speaking to the Herald, the film’s producer Keith “Lily Allen’s Dad” Allen explained that French had been cast purely on the basis of her mathematical skills, or lack of them .

“She’s functionally innumerate, so ideal for the role of someone who uses a Fibonacci series to outline her calculations for Police funding,” he said.

“I mean not everyone can invent a number by adding together the two previous numbers she’s just made up, and get a laugh – in comedy, timing is everything,” he explained.

Allen also confirmed that his first choice for the role of Theresa May is Jennifer Saunders although this remains dependent on her successfully completing a crash diet.

“It’s only one breakfast dalmatian and no chips for Jen, ,” he said adding that Saunders’ husband Ade Edmondson would be playing former former Archbishop of Canterbury Paul Nuttall whatever.

“Actually Ade freely admits that he has been playing Nuttall for years but nobody has yet noticed,” he said.

Allen added that equally unnoticed has been the fact that for the past three years Conservative ministers Michael Gove and Jeremy Hunt have been possessed by the ghost of the late Rik Mayall, in character as Richard Richard from the 90s cult comedy series “Bottom”.

“He’s been in full control of Gove, Hunt, Conservative party policy on Europe and their Brexit negotiation strategy – it’s amazing nobody’s noticed,” said Allen “Then again maybe not,” he grinned.

Still remaining to be cast is the pivotal role of Jeremy Corbyn, with Lenny Henry having confirmed earlier today that he had turned down the chance to play the aging white, bearded Labour leader as at this point in his career he felt it was better to concentrate on serious roles.
