Boris Johnson: petrol crisis and pig cull part of necessary post-Brexit transition

PM's remarks come as Liz Truss insists it's the role of business, not ministers, to resolve such problems

Queues for petrol and mass slaughter of pigs at farms because of a lack of abattoir workers are part of a necessary transition for Britain to emerge from a broken economic model based on low wages, Boris Johnson has argued.

His comments, on the first day of the Conservative conference, came as Liz Truss, the foreign secretary, insisted it was the role of business, not ministers, to sort out such problems.
