Keir Starmer will try to force the mutinous Labour ranks back into line today with a warning that Britain faces a choice between him or Nigel Farage.
The PM will use his keynote speech to party conference in Liverpool to talk up the threat posed by Reform - which is streets ahead in the polls.
He will argue that the UK 'stands at a fork in the road' and can move towards 'decency or division', urging Labour to 'fight'.
The premier will also give a tough message that left-wingers must accept tougher policies in areas such as immigration to appeal to voters.
Sir Keir has endured a devastating month, plumbing record lows for popularity while fears mount about a massive new tax raid in the Budget.
