A huge operation is under way to keep people safe this Spring Bank Holiday as Britain remains on critical alert following the Manchester bombing.
Here are some of the major events expected to go ahead as planned, and some that have been cancelled during the first bank holiday when the national threat level has been at its highest.
Going ahead on Saturday:
FA Cup final, Wembley.
The Duke of Cambridge and Labour leader Jeremy Corbyn are expected to join tens of thousands of Arsenal and Chelsea fans at the north-west London stadium.
The Football Association said enhanced security measures will be in place and fans are urged to arrive at least an hour before the 5.30pm kick-off.
Premiership Rugby final, Twickenham.
Exeter Chiefs battle Wasps in south-west London, with kick-off scheduled for 2.30pm after a minute’s silence for the victims of Monday’s attack. England Rugby advised fans to allow extra time to access the stadium and avoid bringing bags where possible.
Radio 1’s Big Weekend, Hull.
Music fans heading to see Katy Perry, Little Mix, Biffy Clyro and others should allow extra time to undergo two rounds of security procedures. Police will be on hand at checks at transport hubs and a second check will be carried out at the site entrances.
The parade begins at midday with a large number of police officers, specials and police staff on hand to keep the public safe, West Midlands Police said.
Anyone who sees something suspicious is urged to tell a police officer or member of security staff.
Superintendent Phil Dolby said: ‘I appreciate that people planning to attend may feel a sense of nervousness following events earlier this week in Manchester, but I would like to offer some reassurance that a full policing operation is in place and is subject to ongoing reviews.’
Chelsea Flower Show, London.
Visitors on the last day of the show are urged to ‘remain extra vigilant’ and report any concerns to staff or security immediately.
Organisers say they are continuing to work closely with the Metropolitan Police in light of recent events.
Not going ahead on Saturday:
A screening of the FA Cup final at the Emirates Stadium. Arsenal said they reluctantly made the decision following the raising of the threat level.
While Take That’s Manchester Arena gig that was due to take place on Thursday 25 May has been rescheduled for this evening.
Going ahead on Sunday:
Great Manchester Run.
Thousands of defiant runners and spectators are expected to turn out for the 10k race. Participants should have received direct instructions from organisers by email.
Vitality Westminster Mile, London.
Organisers said they are working closely with the Metropolitan Police, the Mayor’s Office and other authorities on additional security measures for runners and spectators on The Mall.
Radio 1’s Big Weekend day two, Hull.
Concert-goers should expect the same security measures as were in place on Saturday.
Not going ahead on Sunday:
FA Cup victory parades: Both Arsenal and Chelsea have said the victors will not stage street parades on Sunday to avoid placing additional pressure on the police.
Chief Constable Ian Hopkins, of Greater Manchester Police, said: ‘Through such a difficult time, we have seen the best from the people of Manchester, who have come together to support each other since the horrific events on Monday night. I have been inspired by their determination, compassion and solidarity that characterises this diverse city.
‘Manchester is a busy place and this weekend we have the Manchester Games, the Great Manchester Run, the Courteeners concert and the start of Ramadan. All these events will be taking place and additional officers, including a significant number of armed officers, will continue to be on patrol.
‘There will be additional security checks at some locations and we would ask people to be patient and work with us to ensure everyone can enjoy these events safely.
‘Manchester has come together this week and it is important we continue to stand together, particularly in relation to hate filled views that have no place in Greater Manchester.’
He added: ‘Finally, it is important to remember that the threat level is still at critical and we do need everyone to remain vigilant in the coming days.’
