Lord Owen reacts to the Prime Minister’s speech In Florence, 22 September 2017.

“I believe the whole country can and should now rally to support this negotiating position.

“We are in the midst of the most difficult international negotiation we have ever faced. Disunity weakens our negotiating hand.

“Brexit is the people’s choice. If politicians play games with this issue they imperil the country.

“Brexit does not belong to the Conservative Party. We need cross-party input into refining and buttressing the all important detail of this new UK position.

“The European Commission will hopefully now start the second stage, building up towards agreement by October 2018.”
