The very first 'very high' pollution alert has been issued in London by mayor Sadiq Khan.

The warnings are being issued at bus stops, tube stations and roadsides in London.

Episodes of pollution with high concentrations occur a few times per year in London, but very high pollution episodes are rare.

Sadiq Khan is calling for the government to devolve powers to London Credit: PA

This is the highest level of alert and everyone - from the most vulnerable to the physically fit - may need to take precautions to protect themselves from the filthy air.

The government urgently need to do their bit. They need to devolve more powers to London and introduce a national diesel scrappage scheme to rid our streets of the dirtiest vehicles. They also need to reform vehicle excise duty and bring in a new Clean Air Act that finally tackles this problem and means that Londoners don’t have to be afraid of the air we breathe.

– SADIQ KHAN, MAYOR OF LONDON

High and very high levels of pollution can cause people with asthma to need to use their inhaler more.

In the capital, the London Air Quality Network run by King's College, London, said the cold, calm and settled conditions over the weekend caused a build up of local emissions from traffic and wood burning, combined with pollution from the continent.

Very high levels of particulates are expected through Monday in London and into Tuesday, with highest levels of pollution expected in the centre of the city and along busy roadsides.
