Louise Haigh, the Transport Secretary, vowed to fix “up to one million more potholes per year” in September.
She also announced a clampdown on “spiralling” car insurance costs in October, launching a task force to look at whether consumers are receiving “fair value for money”.
Ms Johnson said the average cost of fixing pothole damage to cars now stands at £4,000.
“It has become more expensive to repair cars for many reasons, including the cost of parts and specialist labour, so fixing any pothole-damaged car adds to the overall cost that insurers and ultimately consumers face.”
Data from comparison website Moneysupermarket show over the last five years, premiums have risen by 34 per cent on average.
While Rachel Reeves, the Chancellor, announced £500 million for road repairs in October’s Budget, it was unclear whether this was new funding or a portion of the £8.3 billion previously allocated by the Conservatives to local road maintenance, following the cancellation of HS2’s Phase 2 to Leeds.
