How much of the NHS has actually been "privatised"?

There is a lot of debate at the moment about to what extent the NHS has been or might be  "privatised" and by which parties.

There is an excellent fact check on the subject here by Full Facts entitled

"How much more is the NHS spending on Private Providers?"

Among the conclusions

1) The total amount of NHS spending outsourced to private providers has risen slightly over the last decade or so but is still less than 8%.

2) The rate of rise has been similar in the last years of the Labour government, to that under the coalition and majority Conservative governments, and

3) If you take 2010/11 as being the responsibility of the Labour government, the rise was slightly faster in the latter years of that government than subsequently.
