A hospital has launched a campaign to create a smoke-free environment in the area.

The Royal Free London NHS Foundation Trust is urging patients and visitors to Barnet Hospital, in Wellhouse Lane, not to light up when visiting the site.

Smoking is already banned on all hospital grounds, including entrances, car parks and other spaces.

Anti-smoking posters will be put up around the hospital to coincide with National No Smoking Day on March 11.
