Full Fact and LBC now both say the Chancellor, John Healey, will deliver the Budget in the Commons from around 12:30pm today, Wednesday 28 October, after Prime Minister's Questions.
That matches the timing given earlier by FP Markets and Property Week.
Full Fact says the statement will be broadcast live and in full on Parliament Live TV and BBC Parliament.
Full Fact describes it as Labour's third Budget since entering government and Healey's first as Chancellor. It adds that it is the first Budget since Andy Burnham became Prime Minister.
