On May 5 the number of violent teenage deaths since Sadiq Khan’s mayoralty began passed 150.
Mr Khan said work has been done to address the problem, adding: “But there is much more to do and one death will always be one too many. I’m determined to continue making progress by being both tough on crime and tough on the complex causes of crime.”
And while the deaths of so many teenagers is tragic, it is not just young people who are caught up in the violence.
Here is what we know about knife and gun crime in the capital in the last week.

Croydon - Marques Walker sentenced for stabbing 14-year-old Jermaine Cools
Marques Walker, 17, of Jennifer Road, Bromley, was sentenced at the Old Bailey on May 9 after stabbing Jermaine Cools, 14, to death in Croydon in November 2021.
Jermaine was with a group of young people who were fighting in a chicken shop doorway, before Walker drew a knife and repeatedly stabbed him while he was on the ground.
A member of the public drove Jermaine to Croydon Hospital, but he was heavily bleeding, and died later the same evening from his wounds.
Police were searching for Walker, who was caught on CCTV stabbing Jermaine and then fleeing the scene, for six weeks, before finding him hiding behind a bed on December 27, 2021, in relation to a separate matter.
While on the way to the police station he provided his real name, and was then further arrested for murder.
Enquiries later revealed he was a habitual knife carrier, including a conviction for possession of an offensive weapon on school premises.
Walker also pleaded guilty to a separate offence of GBH, after being involved in an attack on a fellow detainee at HMP Feltham on July 1, 2022, which left them requiring life-saving surgery for brain injuries inflicted.
He was sentenced to life imprisonment, with a minimum of 19 years.
Southall - Two teenagers jailed for murdering 16-year-old Rishmeet Singh
Vanusham Balakrishnan, 18, of Waylands, Hillingdon, and Ilyas Suleiman, 18, of St Jeromes Grove, Hillingdon, were sentenced at the Old Bailey on May 10 for the murder of Rishmeet Singh, 16.
Rishmeet, who came to the UK in October 2019 to seek asylum from Afghanistan, was chased and stabbed by Balakrishnan and Suleiman on November 24, 2021, after enjoying an evening with his friends at the park in Southall. He died at the scene.
The two teenagers were arrested in December 2021, with the court hearing how they had gone out on the day of the killing intending to commit murder.
Despite initial reports that Rishmeet was stabbed for the fake Gucci pouch he was wearing, the court heard Rishmeet was killed as Balakrishnan and Suleiman mistakenly believed he was part of a rival gang.
Balakrishnan was sentenced to life imprisonment to serve a minimum of 24 years, and Suleiman life imprisonment with a minimum of 21 years.
