The election campaign was noted for the refusal of Enoch Powell, MP for neighbouring Wolverhampton South West, to endorse Conservative candidate David Bell as he felt that Bell was too far removed from his own policies on immigration and United Kingdom membership of the European Community. Although Powell did not endorse any candidate the National Front claimed that Powell's refusal to support Bell represented tacit endorsement. As a consequence Martin Webster captured 16% of the vote, an all-time high for the NF to save its deposit.
In common with a number of by-elections at the time the Liberal Party did not compete for this seat.
