LONDON: Campaigning for Britain’s referendum on EU membership resumed on Sunday after a three-day hiatus prompted by the killing of a pro-EU lawmaker, but pledges of a more respectful tone were quickly tested by a fresh row over immigration.

Three opinion polls ahead of Thursday’s vote showed the ‘remain’ camp recovering some momentum although the overall picture remained one of an evenly split electorate.

The murder of Jo Cox, a 41-year-old mother of two children, shocked Britain, raised questions about the tone of campaigning and could yet prove a defining moment in what is Britain’s biggest political decision for decades.

Both sides sought to adopt a more measured style on Sunday, paying their respects to Ms Cox but sticking closely to the immigration versus economy debate that has defined the campaign.

“I hope, because of the tragic death of Jo, we can have a less divisive political debate in our country,” Finance Minister George Osborne, a leading conservative ‘remain’ campaigner, told ITV’s Peston on Sunday show.

“Particularly in the last few days of this referendum we’re going to have less baseless assertion and inflammatory rhetoric and more reasoned argument and facts,” he said.

Ms Cox, a Labour Party lawmaker and ardent supporter of EU membership, was shot and stabbed in the street in her electoral district in northern England on Thursday. A 52-year-old man appeared in a London magistrate’s court on Saturday, charged with her murder.

Both the ‘remain’ and ‘leave’ supporters halted their campaigns until Sunday morning.

But the heated nature of the debate — which has so far seen the ‘in’ campaigners accused of scaremongering on the economy and the ‘out’ campaign’s immigration focus criticised as divisive — soon resurfaced after the temporary truce.

Mr Osborne criticised as “disgusting and vile” a poster unveiled by ‘leave’ campaigners last week showing a line of refugees under the slogan ‘Breaking Point’, saying it was reminiscent of literature used in the 1930s.

UK Independence Party leader Nigel Farage, who was pictured in front of the poster, said the EU had failed to control immigration properly and had compromised safety in Europe by allowing in “religious extremists” who wanted to attack Western states.

“Something that is true can’t be a scare, can it?,” Mr Farage told BBC radio when asked about the poster. “It was a comment about us being part of a European Union that is failing.”

The official ‘vote leave’ campaign sought to distance itself from the poster but defended its focus on immigration — an issue that has resonated with many voters.

“The debate in this referendum is about our lack of control over economic migration from parts of Europe whose economies are being destroyed by the euro,” said Vote Leave chairwoman Gisela Stuart. “This is now affecting families in Britain.”

Mr Farage also appeared to indicate he thought Ms Cox’s killing had had an adverse effect on the ‘out’ campaign. “It has an impact on the campaign for everybody,” he told Peston on Sunday when asked whether it would affect the referendum outcome.

“We did have momentum until this terrible tragedy.” The only poll fully carried out since the killing showed support for “in” at 45 per cent ahead of “out” on 42 per cent — a reversal of the three-point lead that the pollster, Survation, showed for ‘out’ in a poll conducted on Wednesday.

Two other polls published on Saturday showed the ‘remain’ campaign had regained its lead over ‘leave’, while another showed the two camps running neck-and-neck.

However, pollsters said most of these surveys were carried out before Thursday’s attack and thus did not reflect the full impact of the event.

“We are now in the final week of the referendum campaign and the swing back towards the status quo appears to be in full force,” Anthony Wells, a director with polling firm YouGov, said.
