LONDON, Sept 26 (Reuters) - The husband of murdered British lawmaker Jo Cox said he was shocked by the fury of the Brexit debate and called on both sides to step back from the inferno of vitriolic rhetoric after Prime Minister Boris Johnson goaded his opponents in parliament.
Jo Cox, a 41-year-old lawmaker for the opposition Labour Party was murdered a week before the 2016 Brexit referendum by Thomas Mair, a loner obsessed with Nazis and extreme right-wing ideology. She was the mother of two young children.
Brexit has illustrated a United Kingdom divided about much more than the European Union, and has fueled soul-searching about everything from secession and immigration to capitalism, empire and modern Britishness.
The rage and ferocity of the Brexit debate has shocked allies of a country that has for over a century touted itself as a confident - and mostly tolerant - pillar of Western economic and political stability.
Cox’s husband, Brendan, said he was shocked by the vicious cycle of inflammatory language on display on both sides in the House of Commons on Wednesday, saying such vitriol risked tipping the United Kingdom towards violence.
When asked how his late wife might have responded, Cox said: “She would have tried to take a generosity of spirit to it and thought about how in this moment you can step back from this growing inferno of rhetoric.”
“To descend into this bear pit of polarization is dangerous for our country,” he told the BBC. “It creates an atmosphere where violence and attacks are more likely.”
Cox was clear that the language on both sides of the Brexit schism was troubling and that the United Kingdom needed to come together rather than tear itself apart.
Some on both sides of the debate are now using the politics of contrived outrage to argue their point: Johnson says parliament is betraying the will of the people over Brexit while opponents cast him a dictator who has ridden roughshod over democracy to take the United Kingdom to the brink of ruin.
Johnson taunted his rivals on his return to parliament on Wednesday, goading them to either bring down the government or get out of the way to allow him to deliver Brexit.
Waving his arms and yelling “come on, come on”, Johnson implored his opponents in a raucous House of Commons session to bring a vote of no-confidence in the government and trigger an election to finally break the Brexit impasse.
Opponents roared “resign” and some cast him as a cheating dictator who should stand aside after the Supreme Court ruled that he had illegally suspended parliament.
“You can disagree with people, you can disagree passionately with people, but you don’t have to impugn their motives whether you a hard Brexiteer or a hard Remainer,” Cox said.
In the June 23, 2016 referendum, 17.4 million voters, or 52 percent, backed Brexit while 16.1 million, or 48 percent, backed staying in the bloc.
But after more than three years of political crisis since the referendum, it remains unclear when, if or on what terms the country will leave the bloc it joined in 1973.
In an uproarious debate in the House of Commons, Johnson refused to apologise for unlawfully suspending parliament and instead attacked opponents for thwarting the will of the people over Brexit.
“We will not betray the people who sent us here; we will not. That is what the Opposition want to do,” Johnson said. “We will come out of the EU on 31 October.”
He provoked ire by repeatedly calling a law that forces him to ask the EU for a Brexit delay unless he can strike a deal as “the Surrender Bill”.
When opposition lawmaker Alison McGovern invoked the memory of Jo Cox and warned Johnson that the political culture was becoming toxic, he said the fever of Brexit had gone on for too long so it needed to be delivered.
After one lawmaker Paula Sherriff told the House she had received death threats, some of which echoed the prime minister’s own rhetoric, Johnson replied: “I have never heard so much humbug in my life”, sparking uproar.
Nicholas Soames, the grandson of Britain’s World War Two leader Winston Churchill, said he was appalled by the tone of the debate and it was the most poisonous atmosphere he can remember in 37 years in parliament.
“I despair to be frank,” Soames, 71, said.
“I have grown up in a house where I believe the job of the prime minister even under very difficult circumstances is to try to bring the country together and what the prime minister did yesterday was to drive it further apart.” (Reporting by Guy Faulconbridge; editing by Andrew MacAskill and Angus MacSwan)
