An operation to insert a pin into former PM Margaret Thatcher's broken upper arm was a success, her son has said.
Sir Mark Thatcher said he was "relieved" and "delighted" that Friday's operation went so well and praised surgeons at the Chelsea and Westminster Hospital, in central London.
Lady Thatcher is expected to remain in hospital until Wednesday at the earliest, said Sir Mark.
The 83-year-old Tory grandee has been recovering in hospital since last week after breaking her upper left arm in a fall.
Doctors decided to insert the pin after the injury failed to heal as quickly as they would have liked.
Sir Mark said the procedure was to hold together the two sides of the fracture which had been "moving about a little bit".
He said general anaesthesia was a concern for anyone of Lady Thatcher's age and added that both he and his sister Carol were "relieved" the operation had been a success.
Miss Thatcher visited her mother on Thursday afternoon, he said, and he had spoken to her by telephone before addressing reporters as he left the hospital.
"I shall be coming back to see my mother when she comes out of recovery," he added.
Sir Mark added: "There is no prospect of her leaving at the weekend. She wants to go home as quickly as possible but that's in the hands of the people in charge of her aftercare."
