I am devastated for the families and friends of those who have lost their lives and those who have been injured.
Clearly something has gone catastrophically wrong and we will work tirelessly and quickly with the emergency services, the tram operator FirstGroup and others to establish the cause. My team will continue to be available in Croydon to assist those affected and the wider community in the area.
The police has set up a telephone number for relatives and friends to call: 0800 056 0154.
I want to thank the emergency services and many others involved in responding.
