Chancellor Kwasi Kwarteng has cut short a trip to Washington and returns to UK for crisis talks over the disastrous mini-budget.
Mr Kwarteng has been in the US capital for this week's global finance minister meetings but is now flying home early to work on the Government's medium-term financial plan.
Liz Truss has been given 17 days to save her premiership by mutinous Tories, with whips said to be warning she could face a leadership challenge if the Chancellor's Halloween financial statement fails to calm the economic turmoil.
