Two of the South East's hospitals have been given top marks in the annual health check carried out by watchdog the Healthcare Commission.
Frimley Park Hospital, Surrey, and the Queen Victoria Hospital in East Grinstead, West Sussex, were both rated "excellent" for services and finances.
But Surrey and Sussex Healthcare NHS Trust, which runs hospitals in Crawley and Redhill, was "weak" on both counts.
It was the second year running the trust was among the worst performers.
It was also one of only four to show no improvement from 2006.
'Up to scratch'
Health Secretary Alan Johnson warned it faced "radical action", including takeover, unless it improved - and he asked the chief executive of the NHS to assess what was being done to "remedy the situation".
Gail Wannell, chief executive of the Surrey and Sussex trust, said that six out of 14 standards in which it failed in 2006 were now up to scratch and that she expected the remaining eight to be so in the coming year.

"The trust has made good progress in reducing healthcare associated infections, with one of the lowest rates of clostridium difficile infection in the South East Coast region," she said.
Frimley Park and the Queen Victoria hospitals, which were among 19 in the country to get top marks, are both NHS foundations, which have a greater degree of local control than other hospitals.
Both had improved since last year.
"I'm delighted that all of the staff's efforts over the year have been recognised in these fantastic results," said Frimley Park chief executive Andrew Morris.
Chief executive at the Queen Victoria Sharon Kearns said: "This provides the perfect platform from which to improve and expand our world-renowned services even further."
