A junior minister says the government's "extremely frustrated" over the UK's hardball approach to Brexit negotiations.
Minister of State for European Affairs, Helen McEntee, says it's not acceptable that Britain's essentially seeking to scrap three years of work.
It comes as more than 30 protests are planned around the UK today, because of Boris Johnson's decision to suspend parliament.
Minister McEntee says the actions of the British government are a concern.
While the British government has insisted it's a routine prorogation to mark the start of a new government, opponents have said it's an effort to limit the amount of time available to potentially pass legislation blocking a no-deal Brexit.
Three court challenges to the planned suspension are underway in London, Belfast, and Edinburgh, while campaigners have called for large protests against Mr. Johnson's move to be held this weekend.
Fears of a no-deal Brexit have intensified in recent weeks, amid the prime minister's insistence that any Brexit deal must see the Irish backstop dropped - a demand which has been rejected by the EU.
Minister McEntee says the impasse will continue unless the UK offers a credible alternative to the Irish backstop.
She says: "We're less than nine weeks out until the Brexit deadline and we're now being asked to essentially wipe the slate clean - wipe three years of negotiations, in particular, focusing on the backstop.
