“It’s a real shame, but this Bonfire Night it’s vital that we put the battle against coronavirus first.
“I know so many of us will want to mark this occasion, but please do not invite friends or family over.
“Sadly, this horrible virus has killed tens of thousands of people, and we need to do everything we can to stop it spreading.
“Our actions now will make a difference and actions of each and every one of us will have an impact.
“Please stick to the restrictions and practice social distancing throughout the lockdown period – for this Bonfire season and during Diwali later in the month.
“Thank you for being considerate and kind to others during the pandemic. This really makes a difference and will save lives.”
"Support is available to people in Brighton & Hove who are struggling because of the coronavirus restrictions.
"This can be with practical things like shopping or with mental health and wellbeing issues."
