British Prime Minister Boris Johnson’s Conservatives have suffered defeat in two parliamentary by-elections

UK Conservatives have lost two crucial seats in England, which could spark concerns about Prime Minister Boris Johnson’s future.

The centrist Liberal Democrat party won the seats of Tiverton and Honiton.

The seats are in a Conservative part of south-west England, where a majority of 24,000 has been overturned.

The Liberal Democrats say it is their biggest ever majority turn around at a parliamentary by election.

The losses have renewed calls for Prime Minister Boris Johnson to resign after a police investigation into gatherings at his Downing Street offices.

Johnson recently survived a vote of no-confidence, which secured his term as Prime Minister for another 12 months.

It also follows the Conservatives winning a landslide majority in three decades during the last national election.
