The Globe Theatre will pause a performance of Shakespeare’s Twelfth Night at 3pm on Sunday for the Government’s emergency alert.
The play is one of many public events that will be interrupted on Sunday as ministers carry out a nationwide test of the service.
The alerts are designed for situations where there is an imminent danger to life, such as during extreme weather events or a terror attack.
At 3pm on Sunday, millions of mobile phones will vibrate and make a siren sound for roughly ten seconds.
There are about 87million mobile phones in the UK and the Government says about 95 per cent of the population has 4G or 5G access.
