It's less than 24 hours before the Radio 1 Big Weekend kicks off at Earlham Park, and with booked-up hotels, DJs arriving and site almost ready, the excitement is building.

The first act on the main stage tomorrow at 1pm is 5 Seconds of Summer, and on Sunday Olly Murs will get the crowd going, joined on stage by Radio 1 DJ Nick Grimshaw.

Presenters have already begun to arrive in the city, with Grimshaw hosting his breakfast show from the Forum in Norwich this morning.

People living near the site can listen out for sound checks, with final preparations under way.

Helen Selleck, Norwich City Council's culture and events manager, said: 'We hope everyone has the most amazing time.

'We'll be capturing all the fun, as it happens, and tweeting from Earlham Park. Happy Big Weekend to one and all!'
