NO2 emissions down by 20% says Mayor

Since the Mayor was elected, NO2 emissions have reduced by 20 per cent and the number of people living in areas exceeding NO2 limits has halved but he fully recognises the need to take further action.

This includes the introduction of the world's first Ultra-Low Emission Zone in central London from 2020, tougher requirements for taxis from 2018 and a £20million fund to tackle local problem areas.

These most ambitious measures will deliver enormous economic and environmental benefits for central London and will make this global city an even better place to live, work and visit.

The toxic gas nitrogen dioxide (NO2) can lead to respiratory disease and can cause the lining of the lungs to become inflamed.

The government is the subject of legal action after failing to deal with the high level of the toxic gas in the country's cities.

Most British cities have plans to reduce traffic fumes to within the legal limit by 2020, however London has insisted that it could not meet the NO2 targets set for it in 1999 until at least 2025.

London has the highest levels of NO2 of any European capital city and the UK has the highest proportion of zones breaching legal limits.

Knifeman had a 'fixation' with Buckingham Palace

Sentencing Belmar to 16 months behind bars, Judge Michael Gledhill said that the knifeman had a 'fixation' with Buckingham Palace.

The potential grave danger, either to yourself or others was obvious by what you did.

There are countless other people in exactly the same situation as you following the relatively recent changes to the country's benefit system.

But they don't all arm themselves with knives and go to Buckingham Palace, intending to trespass within the grounds or enter the palace themselves. That is why what you did could be described as a stunt.

Knifeman jailed for Buckingham Palace break in attempt

A knifeman who tried to break into Buckingham Palace to complain about his benefits being cut has been jailed for 16 months. 44-year-old David Belmar jumped over a barrier armed with a six inch knife in October last year.

Prince Charles is to launch a campaign to boost the numbers of young volunteers in a bid to curb gang violence.

The Prince of Wales told the The Mail on Sunday that street murders can occur because young people lack structured activities.

Charles will join the Prime Minister, the Deputy Prime Minister and the Leader of the Opposition at Buckingham Palace this week along with 50 young people to launch a pledge campaign called #iwill.

Charles said that currently only 29 per cent of young people volunteer regularly, but wants 50 per cent of youngsters aged 10-20 to volunteer by 2020.
