British Labour leader Jeremy Corbyn has ruled out backing a second referendum on a final Brexit deal after suggestions his party could include the policy in their general election manifesto.
His spokesman said: "A second referendum is not our policy and it won't be in our manifesto".
It comes after shadow chancellor John McDonnell yesterday said the government should "put the deal to Parliament and possibly to the country overall" and Mr Corbyn dodged a question on the issue in his first keynote speech of the campaign.
In the speech, Mr Corbyn promised to put wealth "in the hands of the people of Britain" as he focused on big business.
Mr Corbyn cast the 8 June poll as a battle of "the Establishment versus the people", as he promised to overturn a "rigged system" which allowed the rich and powerful to extract wealth from the nation.
A "morally bankrupt" Conservative Party was intent on preserving the system while cutting public services and blaming migrants and the unemployed for the woes of the economy, he said.
And he told an audience of activists in central London: "It is the rigged economy the Tories are protecting that Labour is committed to challenging.
"We will not let the elite extract wealth from the pockets of ordinary working people any longer."
Controversial business figures like Mike Ashley of Sports Direct, Philip Green, Southern Rail and tax-avoiding multinationals should be "worried" about the prospect of a Labour government, said Mr Corbyn.
"Those are the people who are monopolising the wealth that should be shared by each and every one of us in this country," he said.
"It is wealth that should belong to the majority and not a tiny minority."
He vowed: "We will no longer allow those at the top to leech off of those who bust their guts on zero hours contracts or those forced to make sacrifices to pay their mortgage or their rent.
"Instead of the country's wealth being hidden in tax havens, we will put it in the hands of the people of Britain, as they are the ones who earned it."
Mr Corbyn promised he would not "play by the rules" if he won the election, but would take on the "cosy cartels that are hoarding this country's wealth for themselves".
Despite polls putting Labour as many as 21 points behind the Tories, he insisted the election result was not a "foregone conclusion", declaring: "Things can, and they will, change."
While Prime Minister Theresa May sought to frame the election as about Brexit, he insisted it was a battle of "the Conservatives, the party of privilege and the richest, versus the Labour Party, the party that is standing up for working people to improve the lives of all".
Under his leadership, Labour was not part of the "cosy club" at Westminster which thinks it is natural for Britain to be "governed by a ruling elite, the City and the tax-dodgers", he said.
Answering questions from journalists, Mr Corbyn said Labour's manifesto would be "fully costed and will be all accounted for and paid for".
Asked about suggestions that Labour considered the idea of a second referendum on a Brexit deal, Mr Corbyn replied: "The European Union negotiations are going on and we set out our (red) lines on the negotiation.
"Primarily, it's about getting and retaining tariff-free access to the European market.
"We haven't threatened to turn Britain into an offshore tax haven on the shores of Europe, undermining the European economy."
Instead, Labour wants a "good process by which we continue to trade with Europe".
He added: "Walking away and trading under the World Trade Organisation - the manufacturing industry in this country would be extremely damaged."
