A woman from east London says her friend died after her Evangelical Christian pastor told her to stop taking HIV medication.

The woman, who wished to remain anonymous, said a pastor "prayed with her friend and told her to stop taking her medication".

"She passed away. It was a senseless loss," she added.

At least three people with HIV have died after they stopped taking life-saving antiretroviral drugs on the advice of their Evangelical Christian pastors, a BBC London investigation has found.
