The number of confirmed cases of coronavirus in Bolton has risen to 15, according to figures released by Public Health England. 

Yesterday the figure stood at 13. 

Across England there are now 4,257 confirmed cases. The figures are expected to be updated again later today. 

It comes as would-be tourists are being urged to avoid beaches and other holiday destinations in the UK to limit the spread of the disease.

And the National Trust has closed its parks and gardens as of midnight on Saturday night, in fear of crowds attending them on Sunday for Mother's Day.

The moves come as tourist destinations and parks continued to draw crowds on Saturday, despite Government advice for people to avoid non-essential travel amid the worsening Covid-19 crisis.

Cumbria Police said on Saturday that the Lake District and other tourist attractions were experiencing an "influx" of visitors.

The force has now urged people from outside its county to keep away, saying the Lake District is "no longer conducting business as usual", with pubs, restaurants and attractions advised to close.

"Whilst we are looking at all measures to limit the spread of the Covid-19 coronavirus, I must urge people living outside the county not to visit," Cumbria Police's assistant chief constable Andrew Slattery said in a statement.

"A national emergency shut-down of businesses and schools is not an excuse for a holiday."
