I am holding no torch for him. But.I do not regard Dominic Cummings as a general member of the public. So I do think he should be compelled to attend.
1. Is he a civil servant?
2. Does he holds sworn office?.
3. Has his organisation been in reciept of public funds, voted by the government.
Unless the answer is Yes then he is a member of the general public. With all the rights of any other menber of the general public, including a right of not being harassed. He might be invited to meet with , but should not be compelled, members of political parties. Indeed if he is a political activist, would he not relish the opportunity to get his point accross.?
It is easy to assert that we and our friends have our/ their .rights respected, it is less easy to accept that those we dispise have also the same rights.
