Polls open in UK election after campaign marred by attacks

But Mr Cameron then quit as Prime Minister immediately after the United Kingdom voted to leave the European Union in a referendum on 23 June a year ago and he was succeeded by Mrs May last July.

Attacks in Manchester on May 22 and London on Saturday have put the threat from global terrorism at the center of the campaign.

Corbyn planned to address six rallies in England, Scotland and Wales, ending in his home ground of Islington, north London on Wednesday night.

SNP leader Nicola Sturgeon will be joined by her husband Peter Murrell in Glasgow, while Scottish Conservative leader Ruth Davidson and Scottish Labour leader Kezia Dugdale will attend polling stations in Edinburgh.

With formal Brexit talks due to start on June 19, May is hoping to sweep up supporters from the UK Independence Party as well as taking seats from Labour.

"I'm naturally a Conservative voter but I don't agree with the social policy in the manifesto", said voter Patrick Kelly, 60, in east London.

Part of the reason is Britain's electoral system.

"We are seeing the terrorist threat changing, we are seeing it evolve and we need to respond to that", May said.

The surrounding rural areas remain affluent, but the steelworks have closed, to be replaced by retail chains and indoor shopping centers.

The UK's first past the post system - whereby the candidate in each constituency with the most votes, rather than an absolute majority, wins the seat - means that hung parliaments have traditionally been rare, there have only been two since 1970.

In his tweet, Cameron urged his followers to back May and vote for the Conservative party when they head to the polls tomorrow.

People will be casting their votes for the 2017 Election today. "At one point Corby was called little Scotland, now it is called little Poland". She backtracked days later, prompting opposition critics to pour scorn on her central claim to offer strong leadership.

May is on course to increase her majority in parliament in Britain's election on Thursday, opinion polls showed on Wednesday, suggesting her gamble to call the vote to bolster her position in Brexit negotiations will pay off.

"Theresa May, you can not protect communities on the cheap and by disregarding the views of the police", he wrote, two days after the London Bridge attack, in a post alongside a video attacking the Conservatives' record that was shared more than 40,000 times.

"I do not like Theresa May". That idea did not work out too well for the Lib Dems last time around.

Ian Strafford-Taylor, CEO of currency expert FairFX, said: "The markets don't respond well to uncertainty and the political ructions of the last few weeks has led to fluctuations in the strength of the pound".

Ms May responded to the attack with a pledge to crack down on Islamist extremism and strengthen police powers. Writing on Facebook, Khan said the city would take a "zero-tolerance approach to hate crime" in the British capital. And that is the prize ahead if we get Brexit right.

Basing her campaign on the slogan of "strong and stable leadership", she has said she alone could face the 27 other European Union leaders and clinch a deal that would give Britain control over immigration policy while ensuring favorable trading terms.

"They'll be thinking pretty soon about who might be best placed to lead the party into the next election and be looking out for any slip-ups or compromises-betrayals in the Brexit negotiations".

"She says one thing and then says something completely different".

It's unclear whether Britain's anxiety about terrorism will benefit May, as the incumbent prime minister, or whether criticism of her record in government will hit home.

Samantha Turner, 55, works in a corner shop, was equally scathing of Corbyn. "Well, I bet that she's regretting that now".

Opponents were quick to remind voters that May had campaigned for Britain to stay in the European Union before embracing Brexit after the referendum, and that she had insisted for months an election would not be in the national interest before calling one. "He will not make a good deal for Brexit".
