These two pictures show Sir Alan Beith, as he is now known, following his election to Parliament in November 1973.
The bottom picture shows the Liberal MP on his first day at Westminster, while the top photo was taken not long after his victory.
He contested the 1970 General Election in Berwick, but was defeated heavily by the Conservative MP Antony Lambton.
Following his resignation, Sir Alan won the by-election on November 8, 1973, by just 57 votes.
Despite the slim margin of victory, he went on to serve as Berwick’s MP until Parliament was dissolved prior to the election on May 7.
