“Palace in lockdown” tops the Daily Mirror as it reports on the arrest of a man who allegedly threw suspected shotgun cartridges over the gates of Buckingham Palace.

The area around the Queen Victoria monument had to be evacuated so police could carry out the controlled explosion. The paper adds that the incident comes as security services prepare to oversee their “biggest operations in 70 years” at the King’s Coronation on Saturday.

The front page also reports on the Met Gala and features an image of Princess Diana – wondering what life would have been like if she was about to be crowned Queen.
