A hospital trust that's been losing a million pounds a week is to be put in special measures.
South London Healthcare NHS Trust will be the first in the country to be put under the control of a special administrator tasked with putting it back on a viable footing.
The trust, which runs three hospitals, has been criticised over standards of care and has run up deficits of more than £150 million over the past three years.
Despite efforts to improve its financial performance, it is still thought to be on track to lose between £30 and £75 million a year for the next five years.
Its chief executive was informed last night that the trust is likely to be put into the "unsustainable providers regime" which was introduced by the last Labour government but never before used.
Health Secretary Andrew Lansley sent a letter as the first step in the legal process towards installing a special administrator using the powers.
The administrator will take over the board and recommend measures to the Health Secretary to put the trust's finances on a sustainable basis.
The trust runs Queen Mary's in Sidcup, the Queen Elizabeth in Woolwich and the Princess Royal University Hospital in Bromley. It released a statement this evening reassuring patients that services would continue as normal.
Sources close to Mr Lansley said long-standing difficulties had been made worse by Labour's merger of the three hospitals' smaller trusts in April 2009 and by two PFI deals that are now costing £61 million a year in interest.
They say the hospital's deficit last year - covered by money from elsewhere in the NHS budget - was equivalent to the salaries of 1,200 nurses or 200 hip replacements a week.
Liz Wickham sent this report from Queen Mary's in Sidcup, which is one of the hospitals affected.
