That's critical for the whole thing working though isn't it?
Somehow Hunt is claiming he can find enough doctors to fill an extra two days of work even though he's promising a reduction in the hours junior doctors work. It's not possible to magically produce the 40% more doctors he'd need to practically pull it off as they don't exist.
The only way he could make good on his promise of a 7 day NHS is to make up the gap with locums. At agency locum rates the NHS budget would run out pretty damn quick, so it would be necessary to find a way to get locum doctors to work for less. This is it.
It's pretty scandalous, but what can you do? As someone pointed out earlier, there isn't anyone holding politicians to account any more. Large swathes of the public have their opinions prescribed to them by the press without question. The people who own the press all sit at the same table at our politicians.
