All the police forces of London are all working together to keep London safe.

It is unprecedented, but equally these are unprecedented times. These are the biggest threats that London has ever faced in peacetime,

It is quite remarkable...if you look at the scene...which is a scene of some great devastation, that so many people managed to escape from such an awful event.

Our concern would be if the demonstration turns into riots or damage and we have got to be prepared to deal with that.

Crime officers...are now combing the site looking for evidence to find out what happened,

We say that London is open for business. If we don't do that, then the terrorists will have won and that's not what we want,

There are additional bodies ... ... We think there may well be further fatalities.

We will allow and help demonstrators to make their point as we always do in London, ... What we will be firm about is people who are here to make trouble.

It is increasingly clear that there is very little else to recover from the scene,

What we will be firm about is people who are here to make trouble.
