Boris Johnson's bus doodle for Midlands cancer charity

Conservative Party leadership contender Boris Johnson contributed a London bus drawing

The prime minster and one of the contenders to replace her have been doing doodles for charity.

As Boris Johnson hopes Conservative MPs and party members are all aboard his leadership bid, the former London mayor drew one of the city's iconic buses.

Outgoing PM Theresa May, meanwhile, drew something with which she is often associated - not Brexit, but a leopard-print shoe.

The sketches are to be auctioned for The Anna Wilkinson Mockingbird Trust.

More than 60 celebrities - including Labour leader Jeremy Corbyn - have contributed to the project, with entertainers Miranda Hart, Claudia Winkleman and Vic Reeves also involved.

The charity - which organises trips for young West Midlands people who have been diagnosed with cancer - said it had been "overwhelmed" by the response.

A free exhibition and auction will take place on Friday in Worcester.

Mrs May appears to have used a fat marker pen to draw a kitten heel she was fond of wearing, while Mr Corbyn continued the feline theme with a doodle of an "eternally happy cat".

Chris and Wendy Wilkinson set up the charity after their youngest daughter, Anna, died aged 16 of a brain tumour. The cause was named after her favourite book, Harper Lee's To Kill A Mockingbird.

Mr Wilkinson said: "We asked celebrities to spend 'a minute for the Mockingbird'... We hope to raise oodles from doodles!"
