When the Conservatives returned to power in 1970 he was named Home Secretary. After Bloody Sunday in January 1972, he was physically attacked and called a "murdering hypocrite" in the House of Commons by Independent Nationalist MP Bernadette Devlin after agreeing with the army's story that they were firing in self defense during his announcement of an inquiry in the incident. Shortly afterwards he resigned as Home Secretary over his connection to business associates under police investigation but he retained his seat in Parliament.
When the Conservative Party moved into opposition in 1974, Edward Heath was replaced as leader by Margaret Thatcher. She surprised many by appointing Maudling to the post of Shadow Secretary of State for Foreign and Commonwealth Affairs. However she later dismissed him. Maudling remained an MP until his death in 1979.
"There comes a time in every man's life when he must make way for an older man."
