UK Papers Lead with Andy Burnham's Premiership and Heatwave Warnings

Andy Burnham's swearing-in as Prime Minister dominates UK front pages, with The Sun, The Times, the i Paper, and The Telegraph featuring a photo of him taking a selfie with fellow Labour MPs inside Westminster. Both The Guardian and The Times report Burnham will begin setting out policies next week, starting with the economy and devolution. The Financial Times states officials say Burnham will also receive defence and security briefings to prepare for sensitive issues. The Times suggests Burnham's choice for Chancellor is between Ed Miliband, Wes Streeting, and Shabana Mahmood, aiming to avoid appearing 'factional'. The Daily Mail headlines 'Messiah without a Mandate', referencing Burnham's potential unchallenged premiership. The Telegraph's Tim Stanley praises Burnham's lighthearted response to a Tory MP's jibe, comparing him favorably to Starmer. Away from politics, every paper covers the heatwave, with The Guardian warning of rail travel only if essential due to the risk of overheated tracks and electrical failures. A rare red heat health alert is in place for tomorrow and Thursday.

The heatwave's impact on rail services is a concern, with many companies advising against non-essential travel. The extreme temperatures can cause steel rails to expand and increase the risk of overhead wire breaks and system overheating.
