Ask the Government not to invoke article 50 of the Lisbon treaty.

Closed 27,151 signatures

What the petition asks

Parliament is sovereign and, if Brexit wins, the Government will not be legally obliged to invoke the Lisbon treaty to start an EU exit. The vote represents less than 75% of the population and already the leave propaganda has been proving untrue.

Government response · 11 August 2016

The British people have voted to leave the European Union and their will must be respected and delivered.

The British people have voted to leave the European Union and their will must be respected and delivered. Article 50 explicitly recognises that a Member State may decide to withdraw “in accordance with its own constitutional requirements”. It is for the Member State concerned to determine what those constitutional requirements are.
