Remain pact plan.
Sinn Fein has signalled a willingness to co-operate with other pro-Remain parties to challenge DUP Brexiteer candidates if a general election is called.
Party vice president Michelle O'Neill did not rule out electoral pacts with other "progressive" parties to maximise the chances of taking seats in Northern Ireland.
Mrs O'Neill also made clear Sinn Fein would not be reconsidering its Westminster abstentionist policy ahead of any snap poll.
"This election will be about Brexit, this election will be about fighting back very hard, very strong against the Tory/DUP sponsored Brexit that brings nothing good for our people here, nothing good for our economy, nothing good for our peace process," said Mrs O'Neill.
