The daughter of the late Margaret Thatcher has publicly thanked people for their tributes after her death.
Carol Thatcher said "magnificent tributes" had been paid.
The former prime minister died aged 87 on Monday after a stroke. She will have a ceremonial funeral with military honours at St Paul's Cathedral on Wednesday.
More than 2000 invitations were dispatched on Friday. Prime Minister David Cameron is to read a lesson and the Queen and Prince Philip will attend.
Lady Thatcher was prime minister from 1979 - 1990. Her husband Sir Denis Thatcher died in 2003 aged 88.
Ms Thatcher, 59, said in London on Saturday she felt like anyone else who had just lost a second parent.
"It's a deeply sad and rather thought-provoking landmark in life," she said.
"An enormous personal thank you to all the people who have sent me messages of sympathy and support. These have given me strength."
On Wednesday, Mark Thatcher said his family have been "overwhelmed" by messages of condolence from the public after her death.
He said his mother would have been pleased that "they have come from people from all walks of life".
She would also have been "humbled" by the Queen's decision to attend her funeral, he said.
The BBC reports it will be the first funeral of a British politician the Queen has attended since the state funeral of Sir Winston Churchill in 1965.
