A new book, The Incidental Feminist, has claimed former UK Prime Minister Margaret Thatcher reportedly had two affairs.

Thatcher, who held the role from 1979 to 1990, is remembered as having a stable marriage to her husband Denis - but the book claims Thatcher got involved with a former MP and had an earlier affair at the start of her career.

UK correspondent Gavin Grey weighs up the validity of these claims.
