Jim,
"The Chancellor for Remain lied that a Leave vote would require an immediate emergency budget to prevent the economy crashing."
Thast's not "lying" Keith - thay's making a prediction

He said he would call a budget, but then he did not do it.
He was in a position to know, not just predict.

Do those who voted Leave say it still doesn't make the claim? Or do they say it was a lie, but it's all in the past so we needn't worry about it?

I say it was a controversial claim that was openly challenged and debated at the time. Leave said it was false and Remain attempted to justify it, as with many other issues on both sides.
The people then decided who had made the best case.
