Kinnock then resigned as leader and was replaced by John Smith. Smith's leadership once again saw the re-emergence of tension between those on the party's left and those identified as "modernisers", both of whom advocated radical revisions of the party's stance albeit in different ways. At the 1993 conference, Smith successfully changed the party rules and lessened the influence of the trade unions on the selection of candidates to stand for Parliament by introducing a one member, one vote system called "OMOV" — but only barely, after a barnstorming speech by John Prescott which required Smith to compromise on other individual negotiations.
