Author Leo Hickman's mother texted him to say Miliband and his wife Justine Thornton were on her flight to the Mediterranean island, a clubbing hotspot for teenagers and 20-somethings.
My mum just texted to say Ed/Justine Miliband are on her flight to Ibiza (sans enfant). An all-nighter as Pacha to cure post-election blues?— Leo Hickman (@LeoHickman) May 11, 2015
Twitter produced the first images of Miliband getting down to it after he arrived in the most flattering Photoshopping he has ever been subjected to.

This revelation suggested Miliband might well get down to some sick beats (Can someone check this is a saying? - Ed).
Ed Miliband has gone to Ibiza. Our work ex Alex saw the Miliband brothers at a rave in Limehouse a few years before the leadership election.— theQuietus (@theQuietus) May 11, 2015
But it might be more subdued than that. Labour Party sources confirmed to The Independent that Miliband had gone to Ibiza simply to "get away from it all".
