Shabana Mahmood: “Ann’s dedication to public service was decades long, and she was a true servant of her constituents.”

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

Robust debate and criticism are part of this 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.

I would not hesitate to impose further measures on other countries refusing to co-operate.
