While in opposition as health spokesman, Andrew Lansley accepted a donation of £21,000 from John Nash, the chairman of private healthcare provider Care UK and founder of the private equity fund Sovereign Capital, which owns several other private healthcare companies, to help fund his private office, leading to allegations of a conflict of interest. Such companies stand to be the largest beneficiaries of Lansley's bill passed by the Coalition and House of Lords to increase the use of private health providers within the NHS.
