Ed Miliband has also faced renewed criticism from one of his former political gurus, who said the Labour leader currently appeared too immature to lead the country.
Academic Lord Glasman, writing in the Mail on Sunday, said: "At the very time when Labour should be showing the way ahead, it gives the impression of not knowing which way to turn."
Lord Glasman, who has written critically about Mr Miliband before, added "When the Labour battle bus should be revving up, it is parked in a lay-by of introspection. It is time for Ed Miliband to show he is a grown-up politician big enough to lead this country."
