The Tory leader says Labour's negotiations could cost the UK billions; the prime minister questions whether Badenoch has been "properly briefed" on UK security.

His answer was so weak and so waffly, it’s no wonder he needs a voice coach, but he didn’t answer the question I asked him: why the Energy Secretary was not defending our country.”She asked if Mr Miliband refused to “defend UK interests because he’s funded by billionaire eco zealots”.

Keir Starmer and Kemi Badenoch will clash at the Despatch box today when they go head-to-head at Prime Minister's Questions. The Tory leader will have lots to take aim at during a week where Sir Keir has cosied up to the EU in an attempt to strengthen ties with the bloc.
