Graham Norton and Coronation Street star Charlie Condou back National HIV Testing Week

Gay celebrities are supporting National HIV Testing Week.

Figures released last week from Public Health England showed 3,250 gay and bisexual men were diagnosed with HIV last year – the highest ever figure.

One in eight gay and bisexual men in London is HIV positive.

PHE said the figures underline the need to further increase both the numbers and frequency of HIV tests, which is critical to tackling the ongoing high levels of HIV transmission.

National HIV Testing Week is taking place from 22-30 November, followed by World AIDS Day on 1 December.
