Reforms to the UK whiplash laws which have led to sharp rises in motor premiums are in doubt after Prime Minister Theresa May called a snap election for June 8.

Her announcement, which caught the political world off guard, means the proposed overhaul contained in the Prison and Courts Bill will not proceed during the “wash-up” period.

The wash-up refers to the time between announcement of a general election and the dissolution of Parliament.

Insurers overwhelmingly back the reforms, which would reduce car cover premiums and help tackle fraudulent claims.

“Whatever the outcome, the new government must push ahead with reforms to tackle low-value whiplash-related claims and introduce urgent reforms to change the framework for setting the discount rate,” Association of British Insurers Assistant Director Head of Motor and Liability Rob Cummings said.

“The industry can only do so much, and it is important that whichever party is in government after the election, they commit to measures to help lower the cost of car insurance.”
