Currie's "Diaries (1987–92)", published in 2002, caused a sensation, as they revealed a four-year affair with John Major between 1984 and 1988, while both were married to other people. The affair started while she was a backbencher and Major was the government whip in Margaret Thatcher's government. After Major's promotion to Chief Secretary to the Treasury, the relationship ended, but the two remained friends. Currie apparently ceased the affair when it became dangerous and impractical owing to the presence of bodyguards who had to be avoided.
