Keir Starmer is gathering his Cabinet today after bolstering his control of economic policy in an humiliation for Rachel Reeves.
The PM's new-look top team will assemble in Downing Street amid fears the ground is being laid for another brutal tax raid at the Autumn Budget.
The dramatic overhaul yesterday saw Sir Keir poach the Chancellor's deputy to become his own ministerial enforcer, and install two economics experts in No10.
The move came after alarm that the premier was 'blindsided' by the Treasury on plans to slash winter fuel payments and curb benefits - which ended in disastrous U-turns.
But the Tories warned that left-wing 'tax fanatics' had been brought in to conduct a 'radical socialist takeover' as Labour faces a black hole of up to £50 billion in the public finances.
