Does this include Polly Carmichael?
My reading was yes, she's out of the lead role. Relevant quotes from Hannah Barnes's Twitter thread, with my annotations:
a new Interim GIDS Management Board, chaired by the Divisional Director for Gender [of Tavistock - a certain Alisa Swarbrick, according to my searching ]
the current GIDS Executive team will be disbanded. Its members will have roles in workstreams and projects relevant to their skills and experience... The Service Director [of GIDS - ie Polly Carmichael] will have a place on the GIDS Interim Management Board.
