British Prime Minister Boris Johnson on Sunday pledged to take the country out of the EU by January 31, then set about reinvigorating public services as he launched his Conservative Party’s general election manifesto.

Unable to speed his EU divorce deal through parliament after coming to office in July, Johnson is seeking a majority at the December 12 snap vote.

Johnson said his “sensible, moderate, tax-cutting” agenda would help reunite Britain after three years of acrimony following the 2016 referendum vote to leave the EU.

“We’re now, as you know, less than three weeks away from the most critical election in modern memory,” Johnson said as he unveiled the manifesto in Telford, west-central England.

“The choice has never been starker. Get Brexit done and we can restore confidence and certainty to businesses and families.

“Get Brexit done and we can focus our hearts and our minds on the priorities of the British people.

“It is time to unleash the potential of the whole country and to forge a new Britain.”

Johnson is promising to bring back his Brexit deal to parliament before Christmas if the Conservatives return to power in the third general election in four years.

“We can then get the whole thing completed in a matter of days if not weeks, and we’re out by January 31,” he said.

Johnson insisted that the deal will allow Britain to regain control over its laws, money and immigration policy, the pillars of the Brexit deal he negotiated with Brussels in October.

Labour leader Jeremy Corbyn wants to renegotiate a new, softer Brexit agreement within three months and then put that to a referendum alongside the option of remaining in the EU by the end of June.

Corbyn himself would stay neutral during the process.

“He used to be indecisive – now he’s not so sure,” Johnson said, in a dig at his chief rival.

Britain Elects poll aggregator puts support for the Conservatives at 42 per cent, ahead of the Labour main opposition at 29 per cent, the anti-Brexit Liberal Democrats at 15 per cent, the Brexit Party at six per cent and the Greens at three per cent.

Johnson will also benefit from the decision of Brexit Party leader Nigel Farage not to field candidates in the constituencies currently held by Conservative​ Members of Parliament ​(MPs).

Despite the poll lead, Johnson has his weak spots, especially given the years of austerity imposed by Conservative governments since 2010.

He promises to end the years of reining in the budget deficit by pumping billions of pounds into public services.

However, the Conservatives are pledging they will not raise the three main taxes – income tax, sales tax and national insurance contributions to state benefits.

“The Conservatives have yet to be clear about how they intend to meet their substantial spending commitments without either raising taxes overall, increasing public debt or both,” said director-general of the Institute of Economic Affairs Mark Littlewood.

Director of the Institute for Fiscal Studies, Paul Johnson, called the Conservatives’ spending proposals “modest” compared with those of the opposition Labour and Liberal Democrat parties.

“If the Labour and Liberal Democrat manifestos were notable for the scale of their ambitions the Conservative one is not.”

Johnson’s measures unveiled on Sunday included 50,000 more nurses to plug the vacancy gap, more money for childcare support, energy efficiency measures, skills retraining and road upgrades.

Hospital car parking charges in England would be axed for certain patients and the National Health Service (NHS)​​staff.

Johnson is also committed to increasing the NHS budget by £33.9 billion ($43.5 billion) by 2023-24 and has promised a programme of building or upgrading 60 hospitals over the next decade.

He also pledged to recruit 20,000 police officers.

On education, the prime minister announced a three-year plan to increase state-school spending in England by £7.1 billion ($9.1 billion) by 2022-23.

On the environment, Johnson promised to get Britain to net-zero carbon emissions within 30 years.

“Let’s go carbon-neutral by 2050 and Corbyn-neutral by Christmas!” he quipped.

On immigration, he wants to end freedom of movement for EU citizens and introduce an Australian-style points-based system.

The scale of eastern European immigration since 2004 was one of the key drivers of the “leave” vote in the 2016 Brexit referendum.

Corbyn said Johnson had unveiled “a manifesto for billionaires” and was offering only “more cuts, more failure, and years more of Brexit uncertainty”. ​​
