– Campaigning by both sides in the referendum on British membership in the European Union was suspended for a third day as lawmakers prepared for a Parliament session Monday to pay tribute to Labour Party member Jo Cox, who was killed Thursday.

Broadcast appearances are to resume Sunday, with proponents on both sides scheduled to appear on television.

On Saturday, BMG Research published a poll showing that "Remain" was ahead of "Leave" by 46 percent to 43 percent, with 11 percent undecided or preferring not to say. The survey was conducted before Cox was killed.

Prime Minister David Cameron and Labour Party leader Jeremy Corbyn made a rare joint appearance Friday at the site of the attack to praise Cox and call for restraint in the referendum debate. Campaigning for Thursday's vote was suspended after her death was announced.

"We should value and see as precious the democracy we have on these islands where 65 million of us live together, work together and get on together," Cameron said after laying flowers with Corbyn at the spot where Cox was shot. "It is all underpinned by tolerance, so where we see hatred, where we find division, where we see intolerance, we must drive it out of public life, out of our communities."

Cox, 41, was a fervent supporter of Britain remaining in the E.U., as well as a champion of the poor and of Syrian refugees. Thomas Mair, 52, who lives in Cox's district, was charged in Cox's death and appeared in court Saturday.
