TLS signed “Kind regards, yours sincerely, Margaret Thatcher,” one page, 7.5 x 9.5, House of Commons letterhead, April 1, 1966. Letter to Miss Brett and Miss Watson, in full: "I should like to send you my warmest thanks for all your help during the Election campaign and on Polling Day. Naturally, we are thrilled with our local result. To increase our majority from 8,802 to 9,429 at a time when we were losing seats in the rest of the country is a triumph for our organisation and determined fighting spirit. All of us are disappointed with the national result. I thought Edward Heath led us magnificently, and he deserved to do better. I hope we shall all stick together, ready to increase our majority next time and to reap a national victory." Thatcher adds the salutation in her own hand. In fine condition. Accompanied by the original mailing envelope.
