BELFAST (Reuters) - Ensuring that Northern Ireland has a “strong say” in the future on Brexit and is treated no differently to the rest of the United Kingdom would help the Democratic Unionist Party (DUP) back a deal to leave the European Union, its leader said on Thursday.

The small Northern Irish party props up Prime Minister Theresa May’s minority government and has so far voted twice against the divorce deal she struck with the EU.

“What it will take to get the DUP over the line is the fact that Northern Ireland is not left behind, that the constitutional and economic integrity of the United Kingdom is the same and that we have a strong say in relation to what happens in the future,” Foster told BBC Radio.
