The EU referendum, also known as Brexit, took place on June 23, 2016, in which the majority of Britons voted in favor of leaving the bloc.
Mr Blair's latest attempt to talk up the prospects of blocking Brexit came as No.10 was forced to play down the significance of Brexit Secretary David Davis' admission that Britain would have to pay a hefty European Union divorce bill to get a good trade deal.
Prime Minister Theresa May called the snap election in order to bolster her mandate to negotiate the country's exit from the bloc, or "Brexit" as it is popularly called.
The only reason it is not on the table i s because the Tories fear old internal wounds would be reopened if Brexit does not happen, he said. "They do think Brexit means Brexit and, for now, there is no groundswell for a second referendum. This will become apparent to those who voted Remain".
In his article, Blair outlined his views of the current situation in Britain.
He added: "I think public opinion is moving on it. Look, this time past year we were the fastest growing economy in the G7, we're now the slowest".

The savings rate is at its lowest in 50 years.More news: Disabled Amtrak train causing headaches at Penn Station
Blair said political changes on the continent, including the election of Emmanuel Macron in France, have made an alternative to a hard Brexit more likely.
"The members of the eurozone will integrate economic decision-making."Inevitably, therefore, Europe will comprise an inner and outer circle. The French and Germans share some of the British worries, notably around immigration, and would compromise on freedom of movement".
"The reforms are now in the program of Europe", he judged.
Tony Blair has warned that the combination of Brexit followed by a Jeremy Corbyn government would soon leave Britain "flat on our back", arguing that a deeply divided country needs a fundamental rethink of its political ideas.
He says: "Given what is at stake, and what, daily, we are discovering about the costs of Brexit, how can it be right deliberately to take off the table the option of compromise between Britain and Europe so that Britain stays within a reformed Europe?"
"I think it's absolutely necessary that it doesn't happen because I think every day is bringing us fresh evidence that it's damage economically", he told Sky News' Sophie Ridge on Sunday programme.
