Market 'ready' for electric cars

Tesla boss Elon Musk has given the strongest hint yet that the firm is considering "freeing" its patents to help speed up electric car development.

When asked by the BBC's Theo Leggett if he was considering giving technology away, Mr Musk said "you're on the right track".

Mr Musk said he hoped to break down technological barriers to help speed up electric car adoption.

The firm will deliver the first five of its Model S cars to the UK on Saturday.
