Campaigners for the single currency in Britain today unveiled their latest weapon - an online game where users "splat" Eurosceptics such as Iain Ducan Smith and Tony Benn.

The interactive game - from online satirists spinon - opens with a parody of the Dad's Army map of Europe, before allowing players to shoot down anti-Europeans as they appear from their bunkers on a map of the UK.

Among the targets are the former SDP leader and anti-euro campaigner David Owen, and former Tory leader, William Hague, whose "save the pound" campaign did not reverse the Tories' fortunes at the lastgeneral election.

Other victims include Margaret Thatcher dressed as a mummy, Mr Duncan Smith in military uniform and Mr Benn in a dressing gown and pipe.
