People across England hit the town for one last drink on Wednesday evening before a month-long lockdown came into force today.
And scenes became violent in Merseyside following reports police officers were attacked.
Meanwhile images appeared to show punters queuing to get into a Wetherspoon pub on Oxford Street ahead of nationwide pub closures.
From today, all pubs restaurants and non-essential shops will remain closed until December 2 to curb the spread of coronavirus.
It meant that scores of people across the country went out for one last hurrah last night.
Photos from Newcastle showed people posing in their Santa hats as they made the most of their last evening of freedom.
In Leeds, a man and woman were pictured enjoying a drink on a table outside a bar.
And in London, scenes showed outdoor seating packed full of people enjoying their final night out.
But emergency services also dealt with a number of incidents during Wednesday evening.
Hundreds of people gathered at a bonfire in Merseyside, where police officers and firefighters had fireworks thrown at them.
Officers were called to Meadow Crescent, Woodchurch at around 9pm, police said.
Chief inspector Gary O’Rourke said: “Not only did police and fire patrols come under attack on their arrival, which could’ve had catastrophic results, but there was a blatant disregard for Covid-19 restrictions, with hundreds of people in attendance drinking alcohol, mixing with other households and ignoring social distancing.
“We will not tolerate this behaviour and are now looking at a number of lines of enquiry, including examining footage and speaking to witnesses, to ensure robust enforcement action is taken.”
Elsewhere in the country, Sussex Police arrested two men and appealed for witnesses after another man suffered serious injuries in a fight involving around 20 people.
Officers were called to Montpelier Place, Brighton, at 10.15pm.
They took the victim to Royal Sussex County Hospital for treatment, where he remains in a serious condition.
