Here is a what we can expect on the campaign trail today:

Labour will talk up its pledge to end the 8am scramble for GP appointments by training more doctors and updating the NHS app so slots are easy to book and rearrange.

Home Secretary James Cleverly, shadow health secretary Wes Streeting and Keir Starmer will all be out campaigning in the East Midlands during the day.

Shadow health secretary Wes Streeting will be promoting the message, saying his party is also committed to bringing back the family doctor, to give patients continuity.

While Liberal Democrat leader Ed Davey continues campaigning across traditionally Tory heartlands in southern England, his Scottish counterpart will be in the south-east of Scotland.

Alex Cole-Hamilton says his party is focusing its aim on getting the SNP out of power and targeting the Uparty in some key seats ahead of the 4 July ballot.

Reform UK chairman Richard Tice will be in Scotland giving a speech on net zero and “saving the oil and gas industry”.
