A final option is the use of single member constituencies. Within the Venice Commission member states, there are only a handful of countries that opt for this. The most known examples of countries with single-member constituencies are probably the United Kingdom which has 650 single-member constituencies, divided over England (533), Scotland (59), Wales (40) and Northern Ireland (18) ; France, where there are 577 single-member constituencies for the elections of the National Assembly; and the United States which uses 435 single-member constituencies for their House of Representatives . Other examples are Azerbaijan, which divides the country into 125 single member constituencies; the Czech Republic which uses 81 single-member constituencies for its Senate;  Poland which also uses single-member constituencies for the Senate (100) .
