The experience of the UK in the 1950s and 1960s to a large extent has borne out Duverger's thesis and representation in the House of Commons reflected votes cast with a reasonable degree of proportionality. However, with the growing strength of the Liberals (now, after a period as the Alliance (with the Social Democrats), the Liberal Democrats) and nationally-based parties like Plaid Cymru and the Scottish National Party, the effects of the "winner takes all" system has become less predictable. This has also led to a greater distortion of the share of seats in proportion to votes. Figure 1 below shows how the seats- to-votes ratio of the governing party has developed since 1945. A ratio of one indicates no bias towards the winning party.
