Can the private sector of the NHS be worth so much?

Private sector market within NHS worth £20 billion
A recent report by corporate finance advisors, Catalyst has shown that there are huge opportunities for the private sector in the provision of healthcare services.
Increasing private provision of primary and secondary National Health Services, particularly with the roll out of Clinical Commissionin Groups and alternatives to traditionally expensive hospital care, is carving out a market worth a potential £20 billion to the sector, experts forecast in the report.
The report also predicts that when CCGs take over the purse strings next year, taking on responsibility for £80 billion of NHS services in England, they will start buying commissioning support services worth an estimated £1.3 billion.
However, there is strong opposition to the increasing involvement of private companies in healthcare delivery.
