Keir Starmer and Andy Burnham are clashing over defence as the outgoing Prime Minister desperately tries to finalise spending plans before a NATO summit. Mr Burnham, who is on track to succeed Sir Keir as Labour premier as early as July 17, is said to want to decide himself on the vital multi-billion pound package.But Downing Street and Chancellor Rachel Reeves are still adamant that the Defence Investment Plan will be resolved in time for a NATO gathering in Turkey on July 7.That will almost certainly be Sir Keir's last face-to-face encounter with Donald Trump as PM, and turning up effectively empty-handed would be highly embarrassing. The ten-year DIP was originally supposed to be published last autumn, but has been repeatedly delayed amid a furious Whitehall funding row.The DIP will set out how new equipment and defence infrastructure will be funded over the coming decade and follows last June's publication of the wide-ranging strategic defence review. Andy Burnham, who is almost certain to succeed Keir Starmer as Prime Minister, is said to want to decide himself on the vital multi-billion pound package. Sir Keir has repeatedly promised the Defence Investment Plan will finally be published before he meets US President Donald Trump at a NATO summit in Turkey on 7 July
