Parliament must be given a vote on triggering Article 50, say Lords

Parliament should be given a vote on triggering formal negotiations to take the UK out of the European Union, a committee of peers has concluded.

It would be "constitutionally inappropriate" and set a "disturbing precedent" for Prime Minister Theresa May to kick off the talks by invoking Article 50 of the EU treaties without first obtaining the approval of both Houses of Parliament, said the House of Lords Constitution Committee.
