The Supreme Court brought an end to the long-running Brexit case on Tuesday with its judgement that only Parliament, not ministers, can trigger Article 50.

But a challenge is being made in a Dublin court on the formal method of kicking off the UK's exit from the EU.

Daily Politics presenter Andrew Neil heard about the challenge from Jolyon Maugham, one of those bringing the case in Dublin, and Gunnar Beck from Lawyers for Britain, a pro-Brexit campaign group.
