Margaret Thatcher, who resigned as British prime minister in November after a revolt in the ruling Conservative Party, will soon retire as an elected member of Parliament, The Sunday Times reported.

The newspaper noted that her office says the "Iron Lady," 65, has not decided whether to continue to represent the constituency of Finchley in north London.But it quoted aides as saying she would tell Finchley Conservatives next week that she will not contest another election, ending 31 years as a member of Parliament.

Thatcher was prime minister for 11 of those years, holding the office - the first woman ever to do so - longer than anyone this century.

But a revolt over her autocratic style and abrasive hostility to European unity led her to resign last Nov. 28. She was succeeded as Conservative Party leader and premier by John Major, 47.
