The former prime minister launched a desperate plea to Remain voters to uprise and fight back against Brexit on Friday.
LBC presenter Iain Dale fumed at the 63-year-old former Labour leader as he argued that Mr Blair had got the mood of the nation all wrong.
Mr Blair insisted the British people who voted to Leave in the EU referendum done so “without knowledge” last June.
This point agitated Dale who surmised that now even more people are in support of Brexit.

Mr Dale said: “My evidence would suggest that there are more people who have gone the other way, people who voted Remain but seven, eight, nine months on, if there was a referendum tomorrow, would actually now vote to Leave.
“He's essentially saying that people who voted Leave really didn't know what they were voting for.
“I don’t remember anybody in the campaign saying, ‘oh well hang on a minute, if we lose this there should be a second referendum once it’s clear what the terms of exiting the EU would be.
“I think most of us knew exactly what the terms, the main ones, were.
“You certainly think that if we're coming out of the EU, we will have to come out of the Single Market because that's an integral part of the EU, that we would withdraw from the European Court of Justice.

“That is, to me, as clear as night follows day.”
When speaking at a pro-EU event, the former prime minister urged those who voted Remain to rise up and fight against leaving the European Union.
He said: “I accept right now there is no widespread appetite to re-think. But the people voted without knowledge of the true terms of Brexit.
“As these terms become clear, it is their right to change their mind. Our mission is to persuade them to do so.

'It can be stopped, if the British people decide that having seen what it means, the pain-gain analysis doesn’t stack up'
“What was unfortunately only dim in our sight before the referendum is now in plain sight. The road we're going down is not simply hard Brexit. It is Brexit at any cost.”
The LBC host mocked Mr Blair’s chances of the decision being reversed, arguing that the decision has been made and will not be altered.
He finished: “When Tony Blair says: I want people to rise up, what he means is that Remain supporters should persuade Leave voters to reverse their opinions.
“Well good luck with that Mr Blair because I think you’re going to have a long wait before that happens.”
