Hi jupiterbeings,
In respect of your claim that 200 out of 650 MPs have links to private healthcare companies.
I think you might be referring to this article?

To clarify, it states that 200 Parliamentarians have links to private health care companies, this figure includes members of the house of lords, so it is really 200 out of approximately 1400 parliamentarians, rather than 200 out of 650.
Obviously still a worrying statistic.
