Labour obsessed with internal drama, says Badenoch as Tories win by-election
Labour is “obsessed” with internal party “drama” Kemi Badenoch said, as she challenged Sir Keir Starmer and his ministers to instead focus on issues such as energy and national security.
The Conservative leader also said her party’s dramatic by-election win in Aberdeen South “sent a message” in favour of more drilling in the North Sea – and she called for the controversial Jackdaw and Rosebank developments to be given the go-ahead.
She said a green light for the projects would boost the UK’s national security, insisting the UK needs to “drill our own oil in the North Sea, not take oil from Russia”.
She also claimed the win helped show the Tories are a “credible alternative to take over from Labour” at the next general election.

When can Andy Burnham become prime minister?
Andy Burnham is expected to waste little time in challenging Sir Keir Starmer for Labour leadership.
Burnham is now an MP, which means that he can challenge Sir Keir Starmer for Labour leadership, but he is required to have the backing of at least 81 of his party MPs - 20% of their Commons make-up.
He would also be required to have the support of 5% of all local branches or at least three party-affiliated groups - two of which must be trade unions.
If Mr Burnham achieved this, a run-off against Sir Keir would be confirmed, and it would be up to the Labour Party when to hold it. The prime minister's name would automatically be on the ballot.

Burnham says Home Office must address immigration concerns
Andy Burnham has said the Home Office must change course after hearing repeated concerns on the doorstep about the fairness of the immigration system.
He said people were frustrated by what he described as a “cut-price approach to procurement”, which he argued had left some areas feeling treated unfairly and "feeling like HMO Britain".
Burnham said: “These are the kind of changes that we need if we are to give hope to young people growing up in this part of the world.”
He added that local people would always do “the decent thing” and “the compassionate thing”, but said they should not be expected to accept arrangements they see as unfair.
