High levels of air pollution are to hit central London today.

The warm weather is pulling hot air in from France, bringing dense smog with it.

Older people and those with asthma or lung problems are being urged to take extra care.

Air pollution control

Teams of air quality wardens will be out in force today busting the myths around engine idling to crack down on air pollution sweeping across London. It comes as Westminster Council announces their parking wardens will fine motorists who are idling £20 if they don't switch off their engines from May 1st. The City of London Corporation says air pollution contributes to the premature deaths of 4,000 Londoners each year.
