UK elections: How did Tories go from landslide victory to possible record defeat?

The UK votes in a general election on Thursday, July 4, with polls suggesting Rishi Sunak's Conservatives could be on course for a record defeat and near wipeout. It is a stark turnaround from the last election five years ago, which saw the Tories score a landslide victory under Boris Johnson. Laura Carter, lecturer in British history at the Université Paris Cité, joins France 24 to take a look at how the party's popularity declined so quickly.
