The Guardian reports that the Labour Party spent almost £1m preparing for the General Election that didn't happen. They specifically mention Martin Linton.
Meanwhile, Labour candidates in some marginal seats had already printed letters to go out to supporters. One, Martin Linton, who has a majority of 163 over the Conservatives in Battersea, south London, sent out letters to thousands of Labour members and supporters asking for their help. Because of the postal strike, hardly any reached their destinations until well after the election was called off.
