Irish Prime Minister Leo Varadkar called on Friday for the European Union and Britain to find "unique solutions" to their Brexit logjam, including a bespoke customs union.
That would solve the problem of a hard border in Ireland once Britain has left the EU, something that is of great concern to Dublin.
Varadkar, a new face at EU summits since taking office in June, also suggested Brussels may accede to Britain's insistence that a post-Brexit body other than the European Court of Justice oversee bilateral issues, such as citizens rights and aviation regulation.
He said, however, that all these "practical solutions" would need to be asked for and would not be offered.
Varadkar was speaking in the British province of Northern Ireland as part of a drive to find a compromise that would avoid a hugely damaging hard border being erected across the island of Ireland.
