Pride in London’s community advisory board has resigned citing an alleged culture of bullying and a “hostile environment” for people of colour volunteers.The resignation of the board on Thursday follows several directors also resigning, including Pride in London’s most senior black volunteer, deepening a race crisis within the organisation behind the UK’s largest Pride march.The resignation letter calls for new leadership to take the organisation forward and for an independent investigation by the mayor’s office into allegations of marginalisation and bullying.The community advisory board (CAB), made up of 10 individuals, was established in 2012 to advise the directors on questions of inclusivity and help the body meet its commitment to.
