The licence fee payer shelled out a mere £2,500 to listen to Ed Miliband evaluate toilet flushes when he sat in for Jeremy Vine on Radio 2, the Register of Members’ Interests reveals. That means Miliband bagged £500 for two hours work a day, which, to be fair, is an enormous discount on Vine’s reputed £10,000-a-week for the radio show. Vine is therefore worth four Milibands*…

Iain Duncan Smith, who took over the show the following week, is yet to declare any payment. Was he free?

*Didn’t Ed Miliband used to say he wanted to ban MPs from taking second jobs?
