Shabana Mahmood: “The government has already done some work in this area, but I'm sure we will have to go further.”

Today I also announce an independent root-and-branch review of the protective security provided by the state to those in public life.

An attack on any individual in public life is an attack on every one of us, and it is an attack on democracy itself.

Those who enter public life do so to serve. Robust debate and criticism are part of the job. Threats, abuse and violence are not.

In a more dangerous world, we are faced by threats from without and within that target our democracy and our way of life.
