Brexit talks between the Conservatives and Labour are about to close without an agreement, ONA reports citing BBC.
Theresa May and Jeremy Corbyn will now move to a second phase, aimed at agreeing on a process for Parliamentary votes designed to find a consensus.
It comes after Mrs May promised to set a timetable for leaving Downing Streetfollowing the next Brexit vote in June.
Ex-Foreign Secretary Boris Johnson has said he will stand in the Conservative leadership election that will follow.
The UK was due to leave the EU on 29 March but the deadline was pushed back to 31 October after MPs rejected Mrs May's proposed deal - the withdrawal agreement that was negotiated with the EU - three times.
That prompted attempts to find a way to end the impasse through cross-party talks between Labour and the Conservatives.
But BBC Newsnight political editor Nicholas Watt said Tory whips had given up hope of finding agreement with the Labour leader on a Brexit deal.
He said on the other side of the negotiating table "Labour has fears about the durability of a deal agreed with a weak prime minister".
