John Longworth, the co-chairman of Leave Means Leave, which is backed by more than 50 Tory parliamentarians, has warned that the “so-called soft Brexit” pushed for by Mr Clark is undermining Britain’s negotiation strategy.
Writing for the Daily Express online, Mr Longworth, the former director general of the British Chambers of Commerce, has said that in “normal circumstances” Mr Clark would have been sacked for a speech he made earlier this week urging caution with the talks.
The article comes amid growing concern that Remainers are plotting to significantly water down Brexit with the backing of big businesses such as Airbus and BMW which are trying to force Britain to stay under Brussels rule in a customs union.
The move would prevent Britain from being able to create its own free trade deals and force it to accept all the red tape created in Brussels by unaccountable bureaucrats.
Mr Longworth pointed out that Airbus is mostly owned by the French and German governments who are bent on ensuring that Brexit is not a success.
He said: “This is classic of a foreign multinational that clearly cares less about the UK but is trying to dictate our future. Airbus is intrinsically wrapped up in the EU.
“Two major shareholders are the German and French governments. Its Global CEO, a former German Army officer, is a senior figure in the secretive Bilderberg Group, a favourite haunt of one George Osborne and whose recent meeting concentrated on destroying ‘populism’, otherwise known as democracy, in the interests of the global elite.”
Turning on Mr Clark, who has been trying to stop a “no deal” in the Brexit war cabinet, Mr Longworth said: “What is more puzzling is why the likes of Greg Clark (no doubt influenced by his Svengali, Lord Heseltine), and Philip Hammond, should think that supporting businesses who export to the EU over and above the rest of the economy is the right thing to do.
“Perhaps they are thinking of their future non-Executive careers.
“It is even more troublesome that Greg Clark thinks that a so-called ‘soft Brexit’ is acceptable given that this would be in direct contradiction of the Prime Minister’s red lines and, more importantly still, would undermine the manifesto on which he and the Conservatives were elected.
“This manifesto explicitly promised that we would leave the SM, the CU and the jurisdiction of the European Court of Justice.”
He added: “In normal times Greg Clark would be sacked, and justifiably so, but these are not normal times.”
