DUP deputy leader Nigel Dodds says the PM "missed an opportunity" at the EU summit to put forward proposals that could have "improved the prospects of an acceptable withdrawal agreement".

He says "nothing has changed" in respect of the withdrawal agreement.

"Nothing fundamentally turns on the formal ratification of documents which the Attorney General has already said do not change the risk of the UK being trapped in the backstop," he says.

"The DUP has been very clear throughout that we want a deal which delivers on the referendum result and which works for all parts of the UK and for the EU as well.

"But it must be a deal that protects the union.

"That remains our abiding principle. We will not accept any deal which poses a long term risk to the constitutional and economic integrity of the United Kingdom.”
