NHS paying millions for patients to 'go private'

NHS spending on private healthcare has risen since waiting time scandals came to light.
Spending across Scotland rose by nearly 60% last year to more than £40m compared to £25m per year in the two years previously.
The rise in spending on the private sector was largely driven by two health boards, Lothian and Grampian.
