The Mr Men and Little Miss characters are getting a new book based on the London Underground.

The characters will join millions of customers who use the capital's bustling transport network in the new story - Mr Men in London.

Mr Busy will lead a tour of the city's attractions, including Buckingham Palace, Trafalgar Square and the Tower of London.

Transport for London and publishers Egmont announced on Monday that the book from Roger Hargreaves' ever-popular franchise would be released next month.

The hard-working tour guide will lead the characters - including misters Tickle, Small and Tall as well as misses Splendid and Naughty - around the city on tubes, buses and river boats.

The book will cost £2.99 and will be released on June 4.
