​Sadiq Khan has no “coherent strategy” to tackle violent crime in London, a retired senior Scotland Yard officer who used to advise him claimed today.

In a scathing attack, former Metropolitan Police superintendent Leroy Logan accused the Mayor of adopting an “enforcement approach” and failing to properly build trust with communities.

He said: “The results speak for themselves, he is failing and unfortunately there are young people dying on the street because of that.”

His comments come on day two of the Evening Standard’s special investigation into the Mayor’s record in office.

The Khan Audit is examining four areas, including crime,that Londoners rated as their biggest priorities in 2016 when Mr Khan ran for office.

His manifesto promised to “challenge gang culture and knife crime head-on”, with a pledge to restore neighbourhood policing.

But figures show the number of robberies has soared by 22 per cent in the 12 months to July, while knife crime is up 12 per cent. The number of violent offences is up five per cent.

So far this year, more than 100 homicide investigations have been launched. Yesterday a 22-year-old man, named locally as Ismail Tanrikulu, was found shot dead in a Tottenham cemetery. Mr Logan, a former chairman of the Black Police Association Charitable Trust, said he had advised the Mayor on crime policy in the run-up to his election in May 2016.

He said: “I made it clear to Sadiq that his agenda needed to be citizen-focused and the Met had to be accountable. I made it clear you cannot stop-and-search or arrest your way out of the problem; you have to have a partnership approach. But as soon as he was in office he turned his back on a lot of that.”

Mr Logan, an adviser to the all-party Youth Violence Commission which has recommended London adopts a public health-focused model to tackle youth violence, said: “There should be more community engagement, especially with young people.”

He accused Mr Khan of having “no real coherent strategy where you can say that everyone knows where they fit. There is just an enforcement approach. He has a strategy, but it is not getting into the wider holistic approach that you need.”

Mr Logan accused the Mayor of deploying an approach that included “putting fear into the minds of young people on the streets. They are already in fear and trying to scare them is not going to work.”

He added: “The real solution is recognising that our young people are suffering from adverse childhood experiences, they need to be supported around the trauma and the fear and the grooming process they are increasingly victims of. There are growing numbers of youngsters being groomed on a day-to-day basis.”

In July, the Standard launched an investigation into what is driving violence against young people on the capital’s streets. It championed a landmark report from the Youth Violence Commission which recommended that London adopts the public health model that has more than halved the murder rate in Glasgow.

Mr Logan admitted that the Mayor “inherited a poisoned chalice from Boris Johnson”, with crime already on the way up, especially violence and gang-related crime.

He also welcomed the Mayor’s recent support for the public health strategy but said he wanted to see action to implement it.

Mr Logan said: “There should be more community engagement, especially with young people. The £45 million he has pledged does not go far.”

Mr Khan today insisted he did have a holistic approach to violent crime and highlighted his creation of a dedicated Violent Crime Taskforce, with more than 150 officers focused solely on the issue.

He added: “I’ve brought the police together with local councils, charities, community groups and others to work on a public health approach to tackling knife crime.”

Met chief Cressida Dick told LBC radio this morning that crime was “stabilising” after a peak earlier this year.
