Sinead Quinn, owner of Quinn Blakey Hairdressers in Oakenshaw, Bradford, was working when Kirklees Council issued a fine for £4,000 and thereafter two more for £10,000.

It already had £1,000 and £2,000 fines for earlier breaches.

She said on Instagram that she did not “consent” to or accept the fines.

Her salon displayed a poster citing Magna Carta and staying that the shop was under the jurisdiction of “common law”.

The council said in a statement: “We completely understand how tough it has been, and continues to be, for local businesses throughout the Covid-19 pandemic.

“We will do all we can to support them through what has been a devastating period, but it is absolutely crucial for people’s safety that we all follow the latest Covid-19 rules and guidance.”
