Mr Tice, who co-founded pro-Brexit organisations Leave.EU and Leave means Leave, dismissed the predictions hailing the “opportunities” Brexit will bring to the UK.
He said: “The reality is with this, and with economic forecasts – particularly forecast for fifteen years out: garbage in equals garbage out with these economic models.
“These models were produced by the same people who, during the referendum campaign at the Treasury and the civil service, said that within a year we would be in deep recession, we’d lose 500,000 jobs, the tech firms would leave, banks would leave. What a load of absolute rubbish.”
The Government also distanced itself from the forecasts, saying it did not “consider the outcome we are seeking in the negotiations.”
Mr Tice’s rant against the Treasury’s forecasts was met with supporting applause from the BBC Question Time audience in Darlington.
He continued: “We’ve got 400,000 more people employed in this country, record low level of unemployment. We’ve got so much to celebrate and the great thing is that the opportunity is just beginning.
“Here near Darlington, down at Teesport, there is a wonderful opportunity as long as we leave the customs union because that’s crucial.
“We can have a free port and free ports generate thousands and thousands of manufacturing jobs. And that’s a wonderful opportunity because we need to rebalance the economy towards more manufacturing jobs.”
Prime Minister Theresa May acknowledged Britain’s divorce from Brussels was “no small undertaking” but said she was confident of “very constructive” discussions.
The PM insisted the Government’s modern industrial strategy made the UK “more attractive” to foreign investors before announcing plans to strengthen commercial ties with Japan.
She said: “Just today we have seen the Bank of England raise its forecast for UK growth compared with its estimates three months ago.
“As we look ahead of course I recognise that UK’s exit for the European Union is no small undertaking, but importantly it does present an opportunity to strike free trade deals around the world and build on our already strong relationship with Japan.”
