The terms of leaving the EU have changed, according to Lord Mandelson.

Speaking on The Andrew Marr Show this morning, the former European Commissioner for Trade and Business Secretary during the final years of New Labour accused the Government of changing the terms of leaving the EU.

He poured scorn on Prime Minister Theresa May's Lancaster House speech whereby she indicated that Britain would be heading towards a 'hard' Brexit, which means leaving the EU's Customs Union and the Single Market, and hinted that this would cause damage to the British economy.

'People did not know what they were voting for'

The Labour peer said that he respects the country's decision to leave the EU.

But after being asked about support for remaining in the EU dipping to 42 per cent in the opinion polls and being reminded that the House of Commons voted overwhelmingly in favour of triggering Article 50, the legal mechanism for leaving the EU according to the 2007 Lisbon Treaty, he said that Leave voters were also 'having colly wobbles' over their decision to vote for Brexit.

After praising former Labour prime minister Tony Blair's speech to Open Europe, a group which is campaigning for Britain to remain in the Single Market, on Friday, he agreed with his former boss that people had no idea what the terms of leaving were on June 23rd last year and that those in the middle who do not feel particularly passionate about remaining in or leaving the EU are not having 'their views expressed in Parliament' and that he will fight against 'a Brexit at all costs.'

Mandelson lambasted the Prime Minister's 'take it or leave it' approach to the upcoming negotiations with other European countries over Britain's exit from the super-bloc and disagreed with her that 'no deal is better than a bad deal' with the rest of Europe.

However, Change Britain, a pro-Brexit campaign group, published research in The Daily Telegraph that suggests the reason why both the former business secretary and Lord Neil Kinnock, former Labour leader and an ex EU commissioner himself, will both vote against triggering Article 50 is because they receive generous pensions from the EU.

'EU citizens are a negotiating gambit'

Despite this, he said that people should continue to put pressure on MPs from all parties, including Conservative MPs who have given in to the ideological wing of the Tory Party, to speak up against a 'hard' Brexit when asked if he believed the Liberal Democrats were now the only anti-Brexit party.

After boasting that EU citizens played a crucial role in bringing prosperity to this country during New Labour's years in office, he said that after April 2019, when Britain would have left the super-bloc by, there will be 'less trade and levels of immigration will remain the same.'

The former trade commissioner attacked the Government for using EU citizens that live in Britain as a 'negotiating gambit.'

He attacked Boris Johnson, the Foreign Secretary, and David Davis, the Brexit Secretary, for 'fraud' after they suggested that Britain could have the same level of trade and remain a member of the Single Market after Brexit, even though Marr reminded him that the Foreign Secretary never said that.

'Blast from the past'

Liz Truss, the Justice Secretary who appeared on The Andrew Marr Show after the Blairite, said that he is 'needs to move on.'

She added: 'He is behaving as if the referendum never happened. He is a blast from the past.'
