Emily Thornberry has said the Labour Party are "prepared to be the next Government".
She told ITV News that if the exit polls are accurate and the Conservatives struggle to form a Government, Labour are "prepared" to act.
The Labour MP said: "Exit polls have largely been right since 1992 so I think it's probably a good baseline.
"We are prepared to be the next Government.
"We look forward to being the next Government and implementing a highly popular manifesto and making sure that we transform this country which is what we promised to do."
Theresa May is expected to receive a frosty reception when she meets the 1922 Committee later. But what do we know about the group?
The Prime Minister appointed her former leadership rival as Environment Secretary as she confirms her new top team.
He insisted he would be backing Theresa May as leader and has warned MPs to "calm down and get behind the Prime Minister".
