A ROOFTOP demonstration is in progress at the West Oxfordshire polling station where Conservative Party leader David Cameron is due to vote this morning.

Two men scaled the War Memorial Hall in Spelsbury shortly before 6am and unveiled a banner depicting David Cameron as Lord Kitchener in the famous World War I poster.

The 15ft poster reads: "Britons Know Your Place. Vote Eton, Vote Tory".

The two demonstrators, one dressed in a straw boater, swigged champagne from bottles.

Police are at the scene.
