“We’re deeply saddened to hear about last night’s horrific attacks in London and our thoughts are with everyone affected, including the emergency services responding to the incident.
“There are two large-scale events taking place in Greater Manchester today and we would like to assure people that these will still take place, but with additional security in place to ensure the safety of everyone.
“We have dedicated resources at both events, with a significant number of officers from both GMP and colleagues from other forces, some of which will be armed.
“There will be additional security checks taking place and everyone will be searched, including bags. We would ask people not to bring bags if they can, as this will help speed up entry.
“I’d like to remind people that the national threat level remains at severe, which means an attack on the UK is highly likely.
“Please remain vigilant at all times and if you see anything suspicious please call 999."
