Treasury preparing emergency cost of living options for next prime minister

Officials' proposed measures include national insurance cuts and pause to green levies

The Treasury is working on a menu of options to counter Britain's cost of living crisis in readiness for an emergency mini-budget due to take place within two weeks if Liz Truss replaces Boris Johnson as prime minister.

With opinion polls and bookmakers' odds showing Truss the clear favourite to move into 10 Downing Street next week, officials are drawing up plans that would allow the new government to move quickly over bills and longer-term reforms of the energy market.
