The Mayor of London has opened an exhibition of portraits of HIV-positive Londoners by Rankin to coincide with World AIDS Day.
Mr Johnson is calling on Londoners to help tackle HIV in the capital, by breaking down the stigma associated with the disease and urging people to get informed and take responsibility for their sexual health.
"HIV continues to have a major impact on the lives of Londoners and this exhibition shows it can affect anyone," says the Mayor.
"It is our duty to keep HIV on the agenda, but I urge everyone to take personal responsibility to protect yourself and others against the condition. Whether directly affected or not, let's stand shoulder to shoulder, show our support and challenge the stigma."
The Mayor is working with his unpaid HIV ambassador Annie Lennox, who is featured in The Body Shop exhibition at City Hall, to raise awareness and improve attitudes around HIV and sexual health, particularly amongst young people.
The exhibition runs until Friday 10 December.
