Labour leadership contender Owen Smith will today pledge the “biggest boost to living standards for a generation” if he becomes prime minister.
The Welsh MP, who was shadow work and pensions secretary until he resigned in June, will promise pay increases for five million workers.
He launched his bid to oust Jeremy Corbyn last month and became the sole challenger when Angela Eagle dropped out of the contest.
In a major campaign speech, he will outline his plans to improve pay and conditions for workers across the country.
He will also condemn the “perfect Tory storm of falling wages, the watering down of workers’ rights and cruel cuts to social security”.
Mr Smith will say that under his leadership, Labour would commit to raising the current minimum wage to £8.25 and extending it to all adults.
He would also transform the Low Pay Commission into a living wage delivery unit, tasked with ensuring companies cannot get round the increase by reducing overtime or other perks.
And he would establish a High Pay Commission to force mandatory reporting of company pay ratios and consult on the introduction of maximum ratios between top and average earners.
Additionally he would repeal the Trade Unions Act, scrap employment tribunal fees and ban zero-hours contracts.
Mr Smith is expected to say: “For the last six years British workers have experienced a perfect Tory storm of falling wages, the watering down of workers’ rights and cruel cuts to social security, resulting in the sharpest fall in living standards ever recorded for low paid British workers.
“As the next Labour prime minister, I would introduce radical plans to deliver the biggest increase in living standards in a generation.
“I am committed to delivering … a revolution in workers’ rights to give people a strong voice at work.”
