He was first elected in the 1979 general election as the member for Perth and East Perthshire. In 1983 he became MP for the newly-formed Tayside North, a seat he held until being defeated by the Scottish National Party's John Swinney in 1997.

Bill Walker was also implicated in the Cash for Question scandal that involved other Tory MPs but the matter was not taken further when it emerged that he had given the cash to charity.
