British Prime Minister Boris Johnson rallies his Conservative party faithful on Wednesday vowing a far-reaching overhaul to wean the UK economy off cheap foreign labor after Brexit. Shrugging off panic-buying at petrol stations, bare supermarket shelves and retailers warnings of a bleak Christmas to come, the Tory leader says the short-term pain is worth it, according to AFP. "We are dealing with the biggest underlying issues of our economy and society," he is expected to say in his conference-closing speech, according to excerpts released by the party. "The problems that no government has had the guts to tackle before. "Because we are embarking now on the change of direction that has been long overdue in the UK economy," Johnson will say, vowing no return to the pre-Brexit model of "uncontrolled immigration". Instead, British businesses will have to invest in their workers and in technology to push the country "towards a high wage, high skill, high productivity economy". But it will take time to transition, and, in the meantime, the government has grudgingly agreed to a limited number of short-term visas to lure truckers and poultry workers from Eastern Europe. - Climate silence - The government blames the acute labor shortages afflicting the UK economy not on its hardline approach to Brexit but on the coronavirus pandemic. But the supply crisis risks undermining themes that Johnson is set to emphasize in his conference speech, including "levelling up" economic growth and "Global Britain" after the EU divorce. He is also expected to talk up Britains action on climate change and the need for global coordination, ahead of convening the two-week COP26 climate summit in Scotland from October 31. Touring exhibitors stands at the conference on Tuesday, Johnson rode an e-bike, climbed aboard an electric tractor, and played with a puzzle to assemble a zero-carbon energy house. But at the Tory gathering as a whole, the topic of climate change has been relegated to the backburner. Finance Minister Rishi Sunak said on Monday it would be "immoral" to bequeath pandemic-driven debt to future generations, but made no mention of saving those generations from a burning planet. The omission was a "damaging sign" ahead of COP26 in Glasgow, commented Rebecca Newsom, head of policy for Greenpeace UK. "Coughing up more cash for green infrastructure now would save enormous costs later and create millions of new jobs across the UK," she said. Neither did Foreign Secretary Liz Truss reference the C-word -- climate -- in her speech on Sunday, while vowing to support "greener" growth and "clean infrastructure" in developing countries. - The B-word - In contrast, the B-word -- Brexit -- has been a recurrent theme for delegates of Johnsons party, adamant that current problems associated with the EU split will pass. Brexit minister David Frost admonished the "anti-transport, anti-car" lobbys "anti-growth ideologies" and "persistent miserabilism". Interior Minister Priti Patel used her conference speech on Tuesday to promise tougher action against climate protestors who have been blockading roads around London. The prime minister mocked the demonstrators as "irresponsible crusties". But Johnsons COP26 president, Alok Sharma, denied the party was soft-pedalling climate change with less than a month to go before he welcomes delegates from around the world to Glasgow. "Sometimes people dont perceive the Conservatives as leading on this," the former business minister told a small audience on the margins of the main conference in Manchester. "Cabinet colleagues actually understand why its vitally important to get this right," Sharma stressed. "This is a real, real opportunity to create jobs, to create growth, to have a healthier country, a healthier planet."
