The independent fiscal watchdog will deliver a forecast to the Chancellor next week as the Government scrambles to curb the chaos in the markets following the mini-Budget.
The Prime Minister and Chancellor Kwasi Kwarteng held crunch talks with experts from the Office for Budget Responsibility (OBR) this morning which lasted less than 48 minutes.
Richard Hughes, Andy King and Professor David Miles, members of the OBR's budget responsibility committee, were seen walking into No11 at 9.45am. They emerged into Downing Street again at 10.33am.
