Sorry We Missed You has received almost universal praise since its festival debut on Thursday evening, with both the Guardian and the Independent awarding the film five stars.
Sorry We Missed You is released in UK cinemas on 1 November, with a US release date still to be announced.
“We have what we call ‘fake left’ politicians, like Ed Miliband and those who went before him,” said Loach.
Set, like his last film I, Daniel Blake, in Newcastle, Sorry We Missed You tells the story of a former labourer who accepts a new job for a predatory zero-hours contract delivery company.
