I read this piece in Jacobin. Its really sloppy in key parts of it. It seems to rely on an implication that the EHRC are not impartial without any real evidence to back this up. Here is my view on why the EHRC has not investigated the Tories. Yet.

To be honest, that would have been bad for everyone.

Only twice has a Section 20 Investigation been launched:
Labour in relation to Jewish members.
Metropolitan Police in relation to Black Police Officers
Many of the other examples are not clear on who the responsible party is.
Is it the Government or is it the Conservative Party?
