Shaw you are getting very boring.
There are multiple issues at stake over this affair. You deliberately ignore them to pursue a witch hunt.

The fact the police bullied their way into Parliament to search an mp's office does nor appear to concern you.
You overlook the fact that shortly after the event the speaker emphasised that a search warrant is required to ransack offices in Parliament.
When arresting an MP the police are required to write to inform the speaker.
Why did this take 5 days.

For someone continually banging on about the great EU democracy, your being totally oblivious to the implications of the affair, and how it impacts British Democracy astounds me.
It seems clear it is not democracy you are concerned with but scoring cheap political shots.
What a hypocritical fellow you are.
