LONDON, Sept 30 (Reuters) - Prime Minister Liz Truss and her finance minister Kwasi Kwarteng will meet the head of Britain's independent fiscal watchdog on Friday as the government looks to reassure financial markets after days of chaos triggered by planned tax cuts.
Kwarteng unveiled a string of lower taxes last week in a fiscal statement that was not accompanied by forecasts from the Office for Budget Responsibility, and which sent markets into turmoil over investor concern about how the government would pay for the borrowing required for the cuts.
The market turmoil led the Bank of England to intervene with emergency bond-buying to protect pension funds from partial collapse.
Critics, including some in the ruling Conservative Party, say Truss and Kwarteng should have included forecasts from the OBR to reassure markets about where the funding would come from for their proposed 45 billion pounds of tax cuts.
On Friday, they will now meet the OBR's chair Richard Hughes, chair of the Office for Budget Responsibility (OBR), to discuss the budget forecast process and economic and fiscal developments since March, the Treasury said.
A committee of lawmakers in Britain's parliament on Thursday urged Kwarteng to bring forward his budget statement which will include new forecasts by the country's fiscal watchdog.
"We all want the forecasts to be as quickly as they (OBR) can but also .. you also want them to have the right level of detail," City minister Andrew Griffith told Sky News.
Kwarteng has said he would announce a "Medium-Term Fiscal Plan" on Nov. 23 that will give new forecasts and detail the cost of the borrowing and measures to cut debt. He has asked the OBR to produce a first draft of its next economic forecasts on Oct. 7.
The OBR said it had offered to produce a forecast to coincide with his first fiscal statement but were not commissioned to do so. ($1 = 0.9010 pounds) (Writing by Michael Holden; Editing by Frank Jack Daniel)
