Liz Truss energy plan ‘needlessly inefficient and expensive’, says thinktank – as it happened

5.20pm BST

Afternoon summary

• Liz Truss will freeze energy bills at an average of £2,500 a year for two years from 1 October, and has pledged to tackle the root causes of the problems in the UK energy market through plans to increase supply, including the resumption of fracking. My colleagues Jessica Elgot and Peter Walker have the story here.

And Rupert Jones has a summary of what the plans involve.

• Liz Truss raised more than £420,000 in donations for her successful Conservative leadership bid, with the biggest single contribution made by the wife of a former BP executive.

• The prayers of the nation are with the Queen, the archbishop of Canterbury has said, as Britain’s leaders sent messages of support to the monarch, who was put under medical supervision after doctors became worried about her health. There is ongoing coverage of this story on our separate live blog.

.@trussliz and @KwasiKwarteng have cleared out two old-school Whitehall mandarins: Tom Scholar, long standing perm sec at HM Treasury, and Stephen Lovegrove, the national security adviser: assault on what they see as orthodoxy, probably as radical as that of Cummings and Johnson
