Annunziata Rees-Mogg speaks at the launch of Nigel Farage's Brexit Party's European Parliamentary election campaign in Coventry, England, on April 12, 2019 | Neil Hall/EPA-EFE Leading Brexit party candidate vows not to ‘stymie’ EU if elected ‘I did not want to be an MEP,’ says Annunziata Rees-Mogg.

SKEGNESS, England — Annunziata Rees-Mogg — one of Nigel Farage's most high-profile Brexit Party candidates — has pledged not to be a "petty" troublemaker if she is elected to the European Parliament this month.

The youngest sister of leading Tory Brexiteer Jacob Rees-Mogg, who is standing to be an MEP in the East Midlands for Farage's new pro-hard Brexit political party, told POLITICO it is not her job to "stymie" future EU policies.

Her brother, who leads the Brexiteer faction of Tory MPs in parliament, said in April that the U.K. should be as difficult as possible if it remained stuck in the European Union as a result of a long extension to Article 50.

"We could veto any increase in the budget, obstruct the putative EU army and block Mr. Macron's integrationist schemes," he suggested at the time, referring to French President Emmanuel Macron's vision for the future of the bloc.

But his sister, who believes the U.K. should have a clean break with the European Union and leave without a deal, said that, if elected, she would take the role "seriously."

"Fundamentally we have got to leave. It is not our job to stymie policies that the European Union without the United Kingdom wants to go ahead. I will not try and kibosh policies they want to go through, for themselves, but not for us," she said while campaigning in the coastal town of Skegness in the East of England.

"However when it comes to standing up for British interests I will be there absolutely committed and doing everything I can to stand up for the British people. We should have left on March 29, these elections should not be happening. I did not want to be an MEP but if I am elected I will do it as well as I can for the British, not for the Europeans."

Asked about the suggestion the U.K. could block an EU budget, she said: “I think that is hopefully not necessary at all, but it would be petty and really what they want to do is up to them. It is not our place to stop them, we should have already left. We shouldn't have a say at all, they should be allowed to get on with it, as long as they let us leave.”
