A national campaign to stop would-be terrorists travelling to Syria will be launched today, following a dramatic rise in the number of people being arrested after going to the war-torn state.
UK authorities have long expressed fears about aspiring jihadis travelling to Syria for terrorist training, and it is thought that hundreds of Britons have already been there.
Scotland Yard says 40 Syria-related arrests were made in the first three months of this year, up from 25 in the whole of last year.
Senior National Co-ordinator Counter-Terrorism Helen Ball said the campaign is "not about criminalising people, it is about preventing tragedies".
"We want to inform those who wish to genuinely help the Syrian cause how they can do so safely and legally," she said.
Boris Johnson's refusal to endorse cartoons shows the mayor has had a "sense of humour failure", the campaign group behind the posters said.
Clean Air London has released a series of cartoons featuring the mayor as he tries to deal with some of "most important air pollution themes" in the capital.
“We asked the Mayor to endorse the cartoons to stimulate debate on many of the most important air pollution themes in London," Simon Birkett, Founder and Director of Clean Air in London, said.
"Amazingly, Boris’s refusal to do so has done more to promote the cartoons than his endorsement would have done. People may now be laughing as much at Boris’s sense of humour failure as the wonderful cartoons themselves."
A series of posters mocking Boris Johnson for his response to the capital's pollution problems have been released by an environmental campaign group.
The images, commissioned by Clean Air London, all feature the Mayor of London as he attempts to address the key environmental issues affecting Londoners.
Poor air quality is said to contribute to more than 4,000 premature deaths in the capital every year.
Boris Johnson was accused of "dangerous complacency" after he claimed London's air quality seemed "fine" during "very high" levels of pollution earlier this month.
Posters warning commuters about the effect of the Tube strike have appeared at stations ahead of Monday's planned 48-hour walkout.
Talks between London Underground and the RMT union have so far failed to avert the strike.
ITV London's Political Correspondent Simon Harris tweeted:
Artwork from two giants of painting will soon go on display at Christie's Mayfair.
Around 65 works from Gerhard Richter and Sigmar Polke will be displayed together for the first time in 50 years.
The collection includes paintings from their later years, which focus on different techniques.
The cost of living in London is rising faster than elsewhere in the UK, according to a new report. The disposable income of a London worker is well above the national average at £231, but rising costs have resulted in a slowdown in the capital's spending power.
The Asda Income Tracker has found the slowdown in spending power was driven by its dependence on the financial and banking industries, in addition to London's spiraling cost of living.
Homerton University Hospital's Accident and Emergency department is the first to be rated 'Outstanding' by the Care Quality Commission. The Hackney hospital received an overall rating of 'Good'. The commission found it was safe, effective, caring and responsive to people's needs.
The department had consistently met the government's 95% target for admitting, transferring or discharging patients within four hours since April 2013.
