Cherie Blair is to undertake a potentially lucrative lecture tour of the US, her spokeswoman has confirmed.
Cherie Blair is speaking in her capacity as a lawyer
The prime minister's wife has joined Bill Clinton, Henry Kissinger and Bono on the books of the New York-based Harry Walker lecture agency.
A spokeswoman at her Matrix Chambers said she would speak on issues "within her professional expertise" as a human rights lawyer.
Mrs Blair, also known as Cherie Booth, is to visit the US in October.
Fees for an appearance with the agency are reported to go from £25,000 to £160,000 for Mr Clinton.
Details of the tour emerged in a leaked e-mail apparently sent to potential clients of the agency, the Daily Telegraph reported.
It said: "I have exciting news. Cherie Blair, noted British attorney, human rights advocate and the wife of Prime Minister Tony Blair, has agreed to speak under our auspices this fall for a limited number of engagements."
The e-mail is said to quote Mr Blair saying his wife "is an enormous source of strength and an extraordinary person in her own right.
"I never know how she manages with all the different things she does - the work, the family".
