A pair of black silk knickers belonging to Lady Margaret Thatcher fetched £25,000 at a charity auction organised by Sir Geoffrey Archer this week.
Mrs Thatcher first wore the 'lucky' knickers on the night the Belgrano was sunk in 1982 and had them on all through the Falklands War right up until the liberation of Goose Green.
Maggie's sought after bloomers were bought by Sir Humphrey Nonce QC, whose hobby is collecting underwear worn by Conservative Prime Ministers.
Sir Humphrey also has several pairs of underpants that were worn by Sir Anthony Eden during the Suez Crisis in 1956 and is the proud owner of a framed pair of underpants worn by Harold Macmillan while delivering the "Wind of Change" speech in 1960.
Sir Humphrey Nonce started investing in Conservative Prime Ministers' underwear in 1963 after buying a pair of underpants that had belonged to wealthy landowner Sir Alec Douglas Home.
Lord Home had just taken over as Prime Minister after Harold Macmillan was forced to resign with prostate trouble.
Despite discolouring after half a century and being in need of some restoration, Sir Alec Douglas Home's underpants, which were purchased at the bottom of the market, have easily outstripped the FT Share Index.
Sir Humphrey Nonce, who lives in a Norman Shaw house in the Bedford Park Garden Suburb of Turnham Green, fought off heavy bidding from other collectors to capture the prized lot when the hammer came down on Mrs Thatchers knickers.
The delighted High Court Judge is looking to increase his holding in Mrs Thatcher stock and, moths permitting, is planning to exhibit his entire collection to the public at large.
