May said that Britain was facing a new threat from copycat attacks, and "it is time to say 'enough is enough.'" She called for worldwide agreements to curb online extremism, said longer jail sentences might be needed for terrorism offenses and argued that there is "far too much tolerance of extremism in our country".
But as the clock ticks down to polling day on Thursday, these expectations have become clouded by uncertainty. Labour are [10.5] to win most seats while the Tories are [1.1].
Another is that May, who spent Saturday evening at a campaign event in North London with thousands of Hindus - telling them they were "a shining example of how a community can integrate successfully and embrace British values" - might feel there is a specific problem with Muslim integration.
May said the government had "had to take some hard choices across the public sector" to curb spending and reduce the country's deficit, as there was "no magic money tree". "Anything short of 50 seats is going to look a very bad performance for her". On a BBC television special on Friday, Corbyn faced repeated questions about his closeness to Irish republican terrorist groups in the 1980s, when they were in the midst of a bombing campaign. This is fitting as the Tory election campaign, with May's refusal to debate Corbyn and her empty mantras, has been so negative you'd be forgiven for thinking Jose Mourinho was managing it. Several people were killed in the terror attack at the heart of London and dozens injured. Keir Starmer (Labour's Brexit spokesman) is one of the leading lawyers of this country.
The UK Labour party leader has received an important boost from the Vermont senator and leading American progressive Bernie Sanders, who faced off against Hillary Clinton in the Democratic party primaries past year.
As last year's referendum on Britain's European Union membership showed, opinion polls can be hugely unreliable.
But even with campaigning suspended, May made a strongly-worded - and inevitably political - statement in front of her 10 Downing St. office, arguing that "things need to change" in the fight against worldwide terrorism.
But the monolithic image has cracked in the face of an embarrassing policy U-turn and May's starchy public manner. Will they turn out to get their revenge on the elderly Leave supporters who will be voting Tory?
"It has affected perceptions", Paul Howell, a Conservative candidate in northeast England, admitted to AFP after the premier made a visit there last week.
But Mr Khan accused him of deliberately misinterpreting comments in which he urged Londoners and visitors not to be alarmed by the sight of armed police on the streets.
She has sought to steer debate towards the question of who is best suited to get Britain through the arduous negotiations for Brexit. The prime minister called for a tougher stance at home against extremists.
But Brexit - for many a toxic and divisive issue - has featured far less in the campaign than might have been expected.
"These are not American issues, or British issues - these are global issues". "They have all suffered cuts to pay for tax giveaways for the big corporations and the very richest".
The state of the public services, and May's U-turns, also feature heavily in a ska protest song, "Liar, Liar", which reached number four in the United Kingdom charts on Friday.
Aside from the embarrassment to the prime minister, who has been on the job for only 11 months, a cliffhanger vote could undermine the Conservatives' hopes of shaping the agenda and set off a period of political turmoil as parties jostle to form coalitions with a workable number of seats to take power.
The Conservative Party declined to expand on what the prime minister meant by this. He is a divisive leader, however, and some Labour candidates have said they are going out of their way not to mention his name to voters, stressing their own credentials.
