Ed Miliband has Lord Prescott on his back As if Ed Miliband wasn't under enough pressure, the Labour leader now has Lord Prescott on his back, too. The portly former deputy prime minister has been taking a curious interest in Miliband's expenditure on the government credit card during his period at the Department of Energy and Climate Change. In a parliamentary question to Lord Marland at the department, Prezza wanted to ascertain "the date of purchase, amount, supplier and level 3 or enhanced transaction entry of each transaction undertaken by the DECC using the government procurement card" between 2006 and 2011, which takes in Miliband's incumbency from 2008 to 2010. Marland told Prezza that details of credit card expenditure for transactions over £500 have already been posted. They are not, I am assured, particularly startling. Prezza, of course, took umbrage at untrue allegations that he had used his government credit card for everything from dinner at the Cinnamon Club in Westminster to a bowl of chicken chow mein at Chu's China Palace in Hull. Blessed, like all great lawyers, with a keen sense of drama, Geoffrey Robertson, the human rights advocate who is married to Kathy Lette, is trying his hand as a playwright. Mandrake hears that the QC is teaming up with the dramatist David Williamson to write a stage adaptation of his book, The Tyrannicide Brief, which told the story of how John Cooke managed to put together a legal case against Charles I, above, the monarch who had previously been regarded as above the law. It will be performed in May at Gray's Inn Hall, which is arguably a "site specific" venue as Cooke and John Bradshaw, the leading judge at Charles I's trial, were both Gray's Inn men.
