Margaret Thatcher is recovering in hospital after a minor operation to remove a growth from her bladder.
The 87-year-old was taken into hospital on Thursday night, and underwent an operation to remove the growth.
Lord Bell, a friend and former adviser, told the BBC:
"The operation was a complete success and her condition is satisfactory. She'll stay in hospital for a few more days and then she'll go home. She's very tough. The doctors are perfectly happy. They say the operation has been completely satisfactory."
