Lady Thatcher 'in good spirits'
Baroness Thatcher is in "good spirits" in hospital where she is being treated after breaking her arm in a fall, her son said.
Sir Mark Thatcher left Chelsea and Westminster Hospital, west London, after briefly visiting his mother.
Sir Mark said: "She had a very good night and was relaxed and slept well.
"She has had some painkillers but was in very good order and had a bit of mischief about her.
"She's in very good spirits."
Asked when his mother is likely to leave hospital, he said: "That is entirely a matter for the clinicians and we will have to wait and see."
