And one of the PM’s most vocal critics on the government benches is to visit Leatherhead next week.

Rishi Sunak says his decision to allow five more years for sales of new gas boilers and petrol and diesel cars will help those on lower incomes to switch.

But in a joint statement Hounslow’s leader and deputy leader accused the government of backtracking on a climate pledge when what the country needed was doers not delayers.

Meanwhile Lord Deben is expected to lambast ministers when he joins a panel next week at Leatherhead Theatre.

The former Tory minister John Selwyn Gummer chairs the UK’s climate change committee and has accused the government of abandoning Britain’s leading world role.

Thursday’s meeting’s been organised by the Surrey Climate commission.
