BBC announces new David Mitchell comedy, return of Bad Education and Mandy

One of the new series announced is Ludwig, a six-part series starring David Mitchell as John 'Ludwig' Taylor, a man who assumed the identity of his twin brother, DCI James Taylor, when he goes missing. Using the position to help discover his brother's whereabouts, Ludwig – a recluse who designs puzzles for a living – must crack the biggest puzzle of his life.

Meanwhile, Michelle de Swarte will star in six-part series Spent, as a former catwalk model who is on the run, broke and homeless. Despite humble beginnings she has become accustomed to the finer things in life, but her lifestyle choices don’t carry much currency now she's pushing 40 and permanently sofa surfing.

De Swarte also wrote the series and said that having her first commission as a writer for the BBC "seems like some sort of fever dream".

Another new series, Mammoth, has been created by and stars Mike Bubbins, while it is co-written with Paul Doolan. It is about a man of his time called Tony Mammoth (Bubbins), a PE teacher who is presumed to have been killed in an avalanche on a school trip in 1979.

However, when his body is discovered decades later in the present day, Mammoth is miraculously brought back from the dead and has to try and rebuild his life as a PE teacher in modern-day Cardiff. Bubbins has promised "big laughs, from a big character. With quite a big moustache.”
