Seven were killed and 48 were injured when three men launched a horrific terror attack on London Bridge.
The attackers drove a ban into pedestrians on the bridge before stabbing onlookers on the bridge and in nearby Borough Market.
The first victim has been named as Canadian national Christine Archibald, described by her family as a “beautiful, loving daughter and sister”.
Sadiq Khan, the Mayor of London, has invited Londoners and visitors to the city to attend a vigil tonight.
In a statement, Mr Khan said: “The Mayor invites all Londoners – and everyone visiting our city – to come together in solidarity to remember those who have lost their lives in Saturday's attack, to express sympathy with their families and loved ones and to show the world that we stand united in the face of those who seek to harm us and our way of life.
"We will never let these cowards win and we will never be cowed by terrorism.
"Members of the public will be able to lay floral tributes at the flagpoles at City Hall."
