Sir Richard Aikens, who sat in the Court of Appeal from 2008 until 2015, spoke after the leader of the English Democrats political party launched a legal battle claiming that the UK has already left the EU.

Britain was supposed to leave on March 29, but was granted an extension by the EU until April 12 at a meeting last in Brussels last month.

But the English Democrats leader Robin Tilbrook, as well as number of Tory Brexiteers, says the new exit date should have gone before the House of Commons and the House of Lords before it was approved.
