Brexit has undermined the Good Friday Agreement which ended 30 years of violence in Northern Ireland, Irish Prime Minister Leo Varadkar said on Saturday.

"Brexit has undermined the Good Friday Agreement and is fraying the relationship between Britain and Ireland," he told Irish state broadcaster RTE.

The border between Ireland and Northern Ireland after Brexit has been one of the major sticking points in Britain's negotiations to leave the European Union in March next year.

"Anything that pulls the communities apart in Northern Ireland undermines the Good Friday Agreement, and anything that pulls Britain and Ireland apart undermines that relationship," Varadkar added.
