Bosses at a Manchester bar say police told them to stop serving "f******* massive" pizza slices - as they don't class as a 'substantial meal' under new Tier 3 lockdown rules.

Staff at Common told the Manchester Evening News that officers visited the Northern Quarter bar on Friday during a patrol checking if venues were following the new restrictions.

Official guidance says venues in Tier 3 areas can only serve booze alongside a 'substantial meal', which it defines as 'like a main lunchtime or evening meal' or a main course.

But the rules have come under fire for not being clear.

It appears the pizza slices, which Common described as 'f*****g massive' on its Twitter feed, don't fit the bill.

The bar said cops told them the slices 'don't fit the substantial food brief', but claimed they 'couldn't tell [them] what substantial food was'.

The venue's boss labeled rules 'a bit of a joke'

Common boss Jonny Heyes said: "It's just a bit of a joke.

"I don't want to say anything bad about the officers because they had obviously been sent round to check everyone was serving food and adhering to the guidelines.

"But they don't have any information about what actually constitutes a substantial meal.

"They're just winging it. As far as I can tell there is no proper guidance. The government policy is just so woolly, there's no clarity.

"It says a lunchtime or evening meal.

The business argued that its slices are substantial enough to be a meal

"Our pizzas are 22 inches, so a slice is 11 inches long. It's probably as big as a 12 inch pizza."

Common remains open and is now only serving full pizzas.

It's estimated nearly 2,000 venues have had to close in Greater Manchester since the region went into Tier 3 on Friday.

Many of those which have remained open have come up with some  inventive ways of following the new rules.

An unnamed council official told the Sunday Times: "We're finding [the rules] impossible to interpret.

"We've been having some ludicrous conversations with bar owners about pasties, beans on toast, toasties, bowls of chips with gravy.

"What is a substantial meal? Surely that depends on the size of the person? What if they're skinny and they like salads?"

Greater Manchester Police have been contacted for comment.
