A Don Quixote for the age of Twitter:

With his trusty paintbrush, Stefan Gatward has been flying the flag for the English language.

Dressed in a collar, tie and well-polished shoes, the former soldier has been fixing missed apostrophes on grammatically incorrect street signs in Tunbridge Wells.

Reaction on the street was mixed – one neighbour offered him praise, but another, also a soldier, took offence.

Mr Gatward said: ‘He asked me what I was doing and told me I was wrong. He called me a vandal and a graffiti artist.

‘He tried to tell me that the post office would not deliver to the street if you put an apostrophe on the address.’
