In pictures: Prime Minister Boris Johnson's visit to Hartlepool
Prime Minister Boris Johnson breezed into Hartlepool for a pre-election visit.
He was joined by Conservative by-election candidate Jill Mortimer and defending Tees Valley mayoral candidate Ben Houchen as they toured medical diagnostics firm Hart Biologicals, on the Queen’s Meadow Business Park, before he surprised people in Mildenhall Close, on the Fens Estate, with a short walkabout. Here is his day in pictures. Mail pictures by Frank Reid.
