Prime Minister David Cameron took time out from dealing with the crisis in the Eurozone and the phone-hacking scandal to guest-edit this week’s edition of the Big Issue .

The Conservative leader visited the magazine’s offices in Vauxhall, South London, spoke to a group of vendors about selling the magazine and met editorial staff.

Cameron explained his reasons for accepting the invitation to guest-edit the title, writing: ‘First and foremost because it’s a great magazine and it’s a great honour to be asked to edit it.’
