ABERDEEN South MP Ross Thomson broke a promise to toss dead haddock into the Thames yesterday, because he had to run away from Nigel Farage.

The staunch Tory Brexiteer was supposed to be taking part in a bizarre protest against the transition deal agreed between the EU and London.

Thomson, along with many other Leave-backing Tories, is upset with the Prime Minister for effectively agreeing to remain in the Common Fisheries Policy until the end of 2020 in return for getting an implementation deal that will give the UK 20 months after Brexit day to get ready for leaving the EU.

That means in the final year of the transition agreement the UK will have no say in the policy, although the EU has said quotas will not change and there will be “consultations”.

The MP had been due to take part in the symbolic fish hurl along with Jacob Rees-Mogg, the leader of the pro-Brexit European Research Group and colleagues Craig Mackinlay and Anne-Marie Trevelyan.

Thomson was the only MP to board the blue, white and red bedecked boat, Holladays R8.

His fellow parliamentarians all scarpered when ex-Ukip chief unexpectedly turned up.

Speaking to reporters crammed on the vessel, Thomson said: “The great Brexit prize is that we can take back our sovereignty, take back control of our waters on March 29, 2019, when we should be doing that, taking back control, we are within seconds, handing it back to Brussels”.

The Aberdonian, hearing Farage was nearby, abandoned ship, with not a single haddock lobbed.

Farage boarded and promptly chucked a bucket of plaice into the river.

He told Sky News: “They told us they would take back control in 2019 – that is not happening. We are now told at the start of 2021 it may happen.

“I don’t think this government has got the guts or the strength to stand up and take back our territorial waters.”

However, the stunt also led to a number of reports being made to the City of Westminster Council, accusing him of flytipping.

And European Parliament chief Brexit negotiator, Guy Verhofstadt, said if Farage really cared about fishermen, he “should have done his job as a member of the fisheries committee in the European Parliament.”

The Ukip MEP only attended one of the 42 meetings held by the EU’s fisheries committee during the three years he sat on it.

Meanwhile, Thomson, and Rees-Mogg and 12 other parliamentarians, including one from the DUP, sent a letter to Theresa May threatening a revolt in the House of Commons over the “completely unacceptable” transition deal

“The UK should have complete control of all fishing activity within our Exclusive Economic Zone. Leaving the European Union means setting our own fisheries policy from March 29, 2019,” they wrote, adding: “The UK must not remain party to the CFP during the proposed implementation period.”

The issue came up at PMQs, with the SNP’s Drew Hendry, asking May about the joint statement from Michael Gove and Ruth Davidson, released two weeks ago, where they claimed Britain would “leave the CFP as of March 2019.”

He added: “Now, the UK is staying in the Common Fisheries Policy but with no say on quotas – the worst deal imaginable.

“What changed between last week and this week?”

The Prime Minister replied: “We will be working with the fishing industry, both fishermen and fish processors, to ensure that we do see a bright future for the fishing industry.

“I want to see three things: we will take back control of our waters, we will ensure that we do not see British fishermen unfairly denied access to other waters, and we want to rebuild our fishing industry.

She added that it was only the Tories who wanted “out of the Common Fisheries Policy”.

Tory MP Mark Francois asked May to give an assurance that UK “will absolutely and unequivocally take back full control of our waters from 2021”.

May, insisted Brexit would “ensure that we do take back control of our waters.”
