Ed Miliband today came under pressure from his own MPs to lurch left in the wake of the victory for an anti-austerity party in Greece. Senior Labour politicians hailed the 'exciting' victory for the left and demanded an end to 'savage cuts', piling pressure on Ed Miliband to oppose more spending cuts. And Green MEPs said the win by the left-wing Syriza party result  'marks the beginnings of ordinary people standing up to a discredited economic model'. But Tory Chancellor George Osborne warned against 'returning to economic chaos', insisting a change in direction would lead to higher unemployment. Scroll down for video
