First minister says voters being disfranchised because some ballots yet to arrive with school holidays due to begin

John Swinney, the Scottish first minister, has raised concerns that voters are being disfranchised because of delays in receiving postal votes.

Voters in some parts of the UK, particularly Scotland, have not received their postal ballots ahead of the election on 4 July. Postal vote requests are particularly high in Scotland because schools are on holiday next week.
