Statement from the Mayor on London terror attack
"There are no words to describe the grief and anger that our city is feeling this morning.
Tragically, seven people have been killed in this sickening attack, and more than 40 injured, some of them critically.
I am appalled and furious that these twisted and cowardly terrorists deliberately targeted innocent Londoners and visitors to our city who were just enjoying their Saturday night.
I condemn these terrorists in the strongest possible terms. They are barbaric cowards and there is absolutely no justification for their evil and unforgivable actions.
My thoughts are with the family and friends of the victims and everyone caught up in this horrific attack.
I'd like to thank our emergency services who bravely tackled the terrorists and helped the injured. I've been in close contact with the Met Police Commissioner and senior officers throughout the night and will be attending the government's COBRA security meeting.
I'd urge all Londoners to remain calm and vigilant today and over the days ahead. We are all shocked and angry today but this is our city - we will never let these cowards win and we will never be cowed by terrorism."

"The Metropolitan Police are responding to the horrific terrorist attack at London Bridge and Borough Market.
My thoughts are with everyone affected, and I'd like to thank the brave men and women of our emergency services who were first on the scene and will be working throughout the night.
I am in close contact with the Met Commissioner and senior officers and am being kept updated on all developments. I will be attending the government's emergency Cobra meeting later this morning.
London Bridge Station is closed and we are asking people to avoid the area.
The situation is still unfolding and I would ask all Londoners and visitors to our city to remain calm and vigilant. Please report anything suspicious to the police, but only call 999 in an emergency.
We don't yet know the full details, but this was a deliberate and cowardly attack on innocent Londoners and visitors to our city enjoying their Saturday night. I condemn it in the strongest possible terms. There is no justification whatsoever for such barbaric acts."
