Smokers across England have sparked up at work and in the pub for the last time as the ban on smoking in enclosed public places begins.
The new law, which came into effect at 0600 BST, is intended to cut deaths from second-hand smoke.
Scotland, Wales and Northern Ireland already have similar bans in place.
Many venues held farewell events for the final night of smoking on Saturday, while local authorities are preparing to enforce the ban.
Doctors estimate second-hand smoke kills more than 600 people a year.
The government also hopes it will help smokers to quit, and discourage children from taking up the habit.
Fines
England's chief medical officer Sir Liam Donaldson said the ban was a "momentous move" and would prevent the deaths of both smokers and non-smokers.
"We are removing from the air at a stroke 50 cancer causing chemicals, and that's bound to be good news for the exposure to risk," he said.
From Sunday anyone lighting up illegally could be fined £50 - reduced to £30 if it is paid within 15 days.
The figure rises to £200 if an individual is prosecuted and convicted by a court.
Businesses failing to comply with the ban could be hit with fines of up to £2,500. |
