Defence

Houthi strikes have hit Riyadh's airport and Saudi defences failed, so the case for RAF interceptors is strong. But ministers decide for themselves when Parliament gets a vote, and have not published the mission's size, cost or legal basis. The government is partly right.

The energy department has reportedly been told to find more than £2bn for defence, with hundreds of millions to come from the heat pump grant. Defence must be paid for, but cutting the grant itself would hit installers and homes off the gas grid.
