Residents of Bolton have been told not to mix with people from other households after the town’s coronavirus infection rate became the highest in England.
The rules apply to meetings indoors and outdoors, unless a person is part of a support bubble, Bolton Council said.
Bolton is the worst-affected area in the country, with a weekly infection rate of 99 cases per 100,000 people, overtaking Pendle (71.1), Oldham (55.6) and Blackburn with Darwen (48.3).
Comparisons between recent and past cases should be made with caution.
The number of confirmed cases is heavily dependent on how many people – and who – is tested.
This has changed significantly since the start of the pandemic, with the number of tests processed each day increasing significantly.
Community testing has also expanded, whereas previously, access was limited to symptomatic patients and key-workers.

Scotland’s R number is estimated to be between 0.9 and 1.4.
The number could be as high as 1.6 in Northern Ireland.
