In 1990, it was announced that who was to receive the first baronetcy since 1964?

In December 1990, the month after Margaret Thatcher's resignation as Prime Minister, it was announced that Denis Thatcher would be created a baronet (the first such creation since 1964). The award was gazetted in February 1991, giving his title as Sir Denis Thatcher, 1st Baronet, of Scotney in the County of Kent. Thus Margaret was entitled to be called Lady Thatcher whilst retaining her seat in the House of Commons; however Margaret insisted that she preferred to retain "Mrs Thatcher" as her form of address, just as it had been throughout her political career. The baronetcy was a hereditary title that was to be inherited by their son Mark after Denis's death. It was the first British baronetage to be granted since 1964, and no baronetages have been created thereafter. However, Margaret was created a life peeress as Baroness Thatcher (and therefore Lady Thatcher, in her own right) in 1992 after her retirement from the House of Commons.

A baronet or the rare female equivalent, a baronetess is the holder of a baronetcy, a hereditary title awarded by the British Crown. The practice of awarding baronetcies was originally introduced in England in the 14th century and was used by James I of England in 1611 as a means of raising funds.
