Damian McBride offers some more of his helpful advice:

‘Mr Miliband will not survive the televised leaders’ debates trying to have it both ways on every policy from Syria to an EU referendum. The prime minister may be entirely wrong on issues such as HS2, but at least his position is clear.The Labour leader’s attempt to keep his options open is all very well, but to what end? If he thinks he can avoid taking any big decisions until he’s securely installed in Downing Street, Mr Miliband unfortunately hasn’t a prayer.’
