Given what happened today, I think you may be misrepresenting a lot of MPs, or how much they value(d) their own skin.
The Speaker of the House is demanding that police give close protection to every MP. That's what, north of 600, not counting Ministers who already have their own CP teams? I would like to think the response of senior police officers would be along the lines of,
"Jog on. You lot have been cutting us to the bone for years. Every time we warned you we didn't have enough resources and manpower, you told us to stop whinging and do more with less. Well, that loud rustling sound you're hearing? That's the BFO flock of chickens coming home to roost".
However, given they are spunking £200 Million up the wall and having 10,000 coppers stag on each day to protect the Eating Out Greta Thunberg World Championship, I suspect they'll do exactly what they're told. And the police's ability to carry out their core duties - as opposed to Richard Madden Walting - will be further reduced.
