The East End is renowned for its community solidarity in difficult times.
I have been witnessing that solidarity these last 24 hours, as I have been out on the streets meeting local youth and urging calm.
I especially witnessed it in the early hours of this morning, when I responded to an emergency call to visit a family on the Isle of Dogs who had been attacked by gang of thugs.
The family underwent a horrific ordeal. Their windows were stoned. Their door was smashed in. Their cars were burnt. They described the experience to me as like being in a nightmare. They feared for their life.
It was a nightmare they were saved from by their neighbours, who provided refuge in their home to evade the attackers.
And I was only too pleased to use my authority to liaise with the police and ensure 24 hour protection, while we moved the family to into bed and breakfast while we re-house them.
I have been so impressed by spirit of unity our community has shown this last 24 hours. And it makes me feel especially proud last night, when I saw white and Asian neighbours in the Isle of Dogs coming together to support each other in a time of crisis, as good neighbours always do.
