THE Brexit deal negotiated by the Prime Minister puts UK employment and environmental standards in danger, a senior union leader has warned.

Len McCluskey (right), general secretary of Unite, said the deal also fails to secure any form of customs union which he believed was vital to the UK’s manufacturing sector and on which hundreds of thousands of jobs depend.

He said: “With this deal, Boris Johnson has made it abundantly clear that the people he wants to please are the hard right-wing of the Conservative party.

“Not only will we lose the crucial customs union arrangements supporting our manufacturing industry and hundreds of thousands of jobs in this country but by further diluting the legal protections for labour and environmental standards, the Prime Minister has made the laws that underpin workers’ rights and public safety extremely vulnerable in future trade deals.

“Donald Trump will be licking his lips at the prospect of him calling the shots in any potential trade arrangement with the US knowing that Boris Johnson has made it very easy for him to demand that our jobs, food standards and probably our NHS are all put on the negotiating able.

“As ever with Boris Johnson, the issue is can we trust him to act in the national interest? This deal proves that we certainly cannot trust him to protect the interests of working people and I expect that these concerns will be what ultimately means his deal should fail in parliament tomorrow.”

Meanwhile, Philip Hammond said he will not be “duped” into voting for a “heavily camouflaged” No-Deal Brexit.

The former chancellor, who lost the Tory whip when voting for the Benn Act, said the Government needs to give assurances of its serious intentions to negotiate a “high-ambition” future trade relationship with the European Union.

Hammond has expressed concern about how long a Withdrawal Agreement Implementation Bill will take to pass through both houses of Parliament.
