Monday’s funeral service is taking place at St Margaret’s Church, in Bodelwyddan, north Wales, near where Williams grew up and went to school.
They moved to Liverpool as a teenager and began performing in local bars and clubs as The Vivienne – named after their love of Vivienne Westwood clothing – before moving to Gran Canaria as a performer at Sparkles Show Bar.
In 2019 they won the first series of Drag Race UK and became known for their impersonation and character acting, most famously for their impersonation of Donald Trump.
The Vivienne later became the first competitor from the UK series to appear in the American version of the show, competing in series 7 of Drag Race All Stars.
Away from RuPaul’s hit show, Williams also appeared on mainstream television shows including Ant and Dec’s Saturday Night Takeaway, had a guest appearance on Emmerdale and most recently competed on a Christmas special of Blankety Blank.
Police say there are no suspicious circumstances surrounding the death.
A statement from their manager, Simon Jones, asked for privacy for the star’s family and said no further details would be released at this time.
