Boris Johnson is launching the Conservative Party’s election campaign.
The party leader is making a speech from a stage in Birmingham, surrounded by supporters holding signs with messages including “Get Brexit Done”.
Earlier, outside Number 10, Mr Johnson vowed to get Brexit “over the line” and “unleash the country’s potential”, if he was re-elected PM.
Mr Johnson also said he would take the UK out of the EU in January if he is returned to power on 12 December.
At the party’s campaign launch, the Mayor of the West Midlands, Andy Street, opened proceedings, saying the party’s success in the area shows “when Conservatives work together at all levels we can do tremendous things”.
Home Secretary Priti Patel followed, telling a crowd of supporters: “This election is a choice between real change or simply more uncertainty, more dither and more delay.”
Mr Johnson’s plans to grab the headlines for his party’s campaign launch were blown off course by the resignation of a cabinet minister – an unusual event during an election campaign.
Welsh Secretary Alun Cairns has quit the cabinet after claims he knew about a former aide’s role in the “sabotage” of a rape trial.
It comes after two Conservative candidates were forced to apologise for comments about victims of the Grenfell tragedy.
Party chairman James Cleverly said Jacob Rees-Mogg and Andrew Bridgen’s remarks about the actions of Grenfell victims had “caused hurt and distress”, telling BBC Breakfast: “We don’t always get things right and when we get it wrong we apologise.”
Elsewhere, as the starting pistol is fired on five weeks of official campaigning:
- The Green Party has launched its campaign with a promise to invest £100bn a year on climate action for a decade
- The Liberal Democrats have pledged to spend £2.2bn a year on mental health services, funded by a 1% rise to income tax
- Tory MP Andrew Bridgen has apologised “unreservedly” for comments about the Grenfell Fire Tragedy
- Welsh Secretary Alun Cairns resigned over claims he knew about a former aide’s role in the “sabotage” of a rape trial
- Labour’s ruling body have not endorsed Chris Williamson, Stephen Hepburn and Roger Godsiff as candidates for the party
Earlier, the prime minister met the Queen at Buckingham Palace on Wednesday morning, marking the official start of the election period in the run-up to the 12 December poll.
Speaking later outside Downing Street, Mr Johnson said he did not want to call the election but had been forced to act in the face of Parliament’s efforts to block his “great Brexit deal”.
If his “modern and compassionate” party won the election, he said he would take the UK out of the EU within six weeks, a move which would release a “flood of pent-up investment” in the economy.
In contrast, he said a Labour victory would result in another referendum and a second vote on Scottish independence.
“If I come back with a working majority, I will get Parliament working again,” he said.
“Come with us and get Brexit done and take the country forward or spend the whole of 2020 in a horror show of dither and delay.”
Parliament was dissolved – or formally shut down – at just after midnight, meaning all MPs revert to being members of the public. Government ministers keep their posts.
The PM’s audience with the Queen lasted about 20 minutes. While the election has already been approved by MPs, the monarch still needed to sign a royal proclamation confirming the end of the last Parliament.
At his own campaign event, Mr Corbyn said he would be a “very different kind of prime minister” who “only seeks power in order to share power”.
He said Labour is “well prepared and utterly determined” to win power to “transform” the country and said recent comments by Tory candidates about the Grenfell tragedy were “shameful” and suggested his opponents felt there were “above us all”.
He said the election was a once-in-a-generation chance to “tear down the barriers that are holding people back” and to “rebuild” the NHS, schools and the police force.
The Labour leader said his Brexit strategy was to unite people, with a second referendum on a “sensible set of proposals” rather than the “disaster” of a US trade deal with Donald Trump.
Mr Corbyn has previously said a new Scottish independence referendum was not “desirable or necessary” – but the SNP’s Nicola Sturgeon said she believed Labour would give the go-ahead for one if in government.
Wednesday’s dissolution ended the shortest parliamentary session since 1948, with the Commons having met for only 19 days since the state opening on 14 October.
