Mr Varadkar said he would be "flexible and reasonable" when attempting to solve issues with the Northern Ireland protocol.The protocol is a part of the Brexit deal that keeps Northern Ireland aligned with some European Union trade rules.Power-sharing in Northern Ireland is currently in a state of flux as a result of a Democratic Unionist Party (DUP) boycott of Stormont in protest over the protocol.However, he said this was also true of Brexit which was imposed without cross-community consent.Mr Varadkar said the protocol had worked without being fully enforced which is "why I think there's room for flexibility and room for changes"."
