How are Select Committees Ineffective?

-They can only ADVISE. This means their Decisions are non-binding and so Government doesn't have to do anything about it -Sometimes, their power to summon Witnesses and for them to tell their truth is Confusing. Theresa May blocked the Home Affairs Committee from interviewing the Head of MI5 Andrew Parker. Dominic Cummings refused to go to the Culture Committee. Only the committee on Privileges and Standard can order the Attendance of anyone. -Government Party having a majority on these Committees means they are not as Independent as they can be. Jeremey Hunt being the Chair of the Health Select Committee in 2020 had raised doubts into how much Scrutiny he would give to the Department, given he was last in that post. -Sometimes, there is bitter in the Committee. The Exiting the EU Committee did not have the parties working together. Conservative Committee Members publically, in 2018, called it out for being Too Remain. Boris Johnson could have a good reason to Ignore their Recommendations -Being promoted to the Government can still be a barrier to making Proper Scrutiny. Being lulled into a Government Payroll Job and all the entitlements threatens the Independence of the Committee. Hunt perhaps?
