Ireland's deputy PM has warned governments doing trade deals with the UK that it is a nation that "doesn't necessarily keep its word".

Leo Varadkar made the comment after Dominic Cummings suggested the UK had always intended to tear up the Brexit deal it signed with the EU in 2019.

Boris Johnson's ex-adviser said the plan had been to "ditch the bits we didn't like" after winning power.

Mr Johnson fought the 2019 election on a "Get Brexit done" platform.

During the campaign, he repeatedly claimed the withdrawal agreement he had negotiated with Brussels – including the Northern Ireland Protocol – was a "great" deal that was "oven ready".

  • EU to offer fewer NI border checks on British goods
  • EU to table new proposals for NI Protocol
  • Will NI protocol talks lead to truce or trade war?

The UK now wants to change the deal to allow goods to circulate more freely between Great Britain and Northern Ireland.

EU officials are travelling to London later to present their proposals for the border – but they are unwilling to rewrite the protocol and their proposals are unlikely to satisfy Brexit minister Lord Frost, who laid out the UK's plans for an entirely new protocol on Tuesday.


Mr Cummings – who has turned against Mr Johnson since being removed from Downing Street at the end of 2020 – claims the prime minister never understood what the withdrawal agreement really meant.

He tweeted: "What I've said does NOT mean 'the PM was lying in General Election 2019', he never had a scoobydoo what the deal he signed meant.

"He never understood what leaving Customs Union meant until November 2020."

When the prime minister did finally comprehend, said Mr Cummings, "he was babbling 'I'd never have signed it if I'd understood it' (but that WAS a lie)".

The former Vote Leave campaign chief said that when Mr Johnson entered Downing Street in 2019, the country was facing the "worst constitutional crisis in a century" with much of what he called the "deep state" angling for "Bino" [Brexit in name only] or a second referendum.

"So we wriggled through with best option we could and intended to get the trolley [his nickname for Boris Johnson] to ditch bits we didn't like after whacking [Labour leader Jeremy] Corbyn. We prioritised," he said.


In July this year, Mr Cummings told the BBC's Political Editor Laura Kuenssberg the Irish government had also wanted to "fudge things" and "it suited both sides to sign up to something that was not what either side had really wanted and which punted difficult questions into the future".

Media caption, The Brexit divorce deal was "inherently self-contradictory in various ways" says the PM's former chief adviser.

In his latest tweets, Mr Cummings dismissed suggestions that abandoning elements of the deal would mean breaking international law.

"Our priorities meant e.g. getting Brexit done is 10,000 times more important than lawyers yapping re international law in negotiations with people who break international law all the time," he said.

Mr Varadkar told RTE television: "I hope Dominic Cummings is speaking for himself and not for the British government.

"But those comments are very alarming because that would indicate that this is a government, an administration, that acted in bad faith and that message needs to be heard around the world.

"If the British government doesn't honour its agreements, it doesn't adhere to treaties it signs, that must apply to everyone else too.

"At the moment they're going around the world, they're trying to negotiate new trade agreements…

"Surely the message must go out to all countries around the world that this is a British government that doesn't necessarily keep its word and doesn't necessarily honour the agreements it makes.

"And you shouldn't make any agreements with them until such time as you're confident that they keep their promises, and honour things, for example, like the protocol."
