The Independent MP for Clacton, who sensationally quit Ukip after already defecting from the Conservatives, described Britain’s long-term membership of the Brussels club as “a tragic mistake”.
He was speaking at the Institute of Economic Affairs, as he explained Eurosceptics had been seen as “extremists” by many up until the recent referendum vote.
He questioned: “If we live in a democracy, why did it take 40 years to correct the tragic mistake of Foreign Office Man, the elites, the Official Mind?”
Douglas Carswell wondered why it has taken so long for the UK to leave the 'failing' EU
If we live in a democracy, why did it take 40 years to correct the tragic mistake?
“We joined the world’s only declining trade bloc, we joined a bloc that when we went in it counted for about 25 per cent of all global patents.
“Today, it accounts for about four per cent of global patents. We joined a continent that is organised by grand design and it’s visibly failing.
“Its EU grand design is a disaster, its trade quotas are a disaster, its agricultural policies are a disaster, why did it take us 40 years to correct the error of the elites?”
The Clacton MP was giving a talking on Tuesday evening
Mr Carswell, who was a founding member of the Vote Leave campaign, described his battle to rid the UK from the shackles of the EU as a “long march”.
He added that Brexiteers had “only just pulled it off”, but was adamant this was the wake-up call those in power needed.

“I think the real issue on June 23rd was the demos reminded the elite this is actually our country, it’s a democracy and the Kratos answer to the demos.
He added: “It’s a wonderful thing.
“But I think we need to ask some quite disturbing questions as to why it took so long and even now the official mind is so reluctant to accept the verdict of the people.”
Meanwhile, Mr Carswell sparked a new row with his former party after he suggested Ukip should “disband” after the UK’s successful campaign to leave the bloc.

In a separate talk on Tuesday, he argued if “you’ve won a battle or war” you “go home and reach out to the people that you beat and you try and win peace”.
The remarks were shot down by a Ukip spokesman, who argued Theresa May could not be left to deliver a successful Brexit.
He said: “Though he might trust this Government to deliver, the signs are it will fail to deliver the clean Brexit that the country demands.
“It is a foolish general who disbands before the end of the process. There again, if he feels that way, why hasn't he resigned his seat?”
