Just another of Theresa May's many divisive, repressive and anti-democratic initiatives. Just because there was a SIS failure in connecting the visit to Libya by the brother of the Manchester Arena bomber and identifying the bomber's activities, she instituted the Commission.
'The Commission for Countering Extremism is a British government agency created under Prime Minister Theresa May in response to the 2017 Manchester Arena bombing, itself part of a wave violent 21st century attacks incited by extremist ideologies.
The idea was mentioned in the 2017 election platform of the Conservative Party, released four days before the Manchester bombing attack. May described the Commission as "a statutory body to help fight hatred and extremism in the same way as we have fought racism." Sara Khan was named head of the new commission in 2018.'
She's there until 2021. She seems to have been very successful in gaining access to the PTB and being given their appointments within the last ten years or so and she is only 39 now.
