The public election is a basic feature of a democratic country. However, the elections differ in each country. The United Kingdom is divided into electoral regions called constituencies and each one elects one representative into the House of Commons. In Slovakia, there is a single electoral region, with an only formal kind of division. After the elections an overall average is made to determine the final result. In Britain, the people vote for individual representatives of their constituency, in Slovakia, we basically vote for parties instead, not representatives of one's area, because the order of preferred representatives of each party is specified by the party itself and made public, well before the elections. This list is usually not created on the basis of regions or areas. The elections into the House of Commons are called in the United Kingdom general elections. Each constituency sends one representative into the House of Commons, which is the one that gained the highest number of votes (first-past-the-post system). Each voter can vote for only one candidate. There are now 646 representatives in the House of Commons, so equally, there are 646 constituencies. The number was last amended for the election in May 2005, from the previous 659, because of certain boundary reviews in Scotland, which reduced the number of the seats held by Scotland by 13. The reason was that England's population is growing more rapidly than Scotland's. Concerning the division, we find 18 constituencies in Northern Ireland, 59 in Scotland, 40 in Wales and 529 in England. The boundaries of the constituencies are determined by the so called Boundary Commission. There's one commission for England, Scotland, Wales and Northern Ireland, currently established under the Parliamentary Constituencies Act from 1986. Each constituency has its own Boundary Committee which submits to the Electoral Commission recommendations for a new redistribution, if necessary. The reviews are being made periodically. The actual rules give a fixed number of representatives for Northern Ireland and a minimum number for Scotland and Wales. It was established by the Parliament that the number of constituencies in Great Britain (England, Wales, and Scotland) mustn't be higher or lower than 613, of which a minimum of 35 has to be from Wales. The Orkneys and Shetlnads cannot be combined with any other areas and Northern Ireland has to have 16 to 18 constituencies. The boundaries are being changed according to the principle of roughly 70.000 voters in one constituency and some 90.000 residents. The review used to take place in a 8-12 years period. There are two types of constituencies: borough (in Scotland 'burgh') and county constituencies. The first type is defined by predominantly urban character, the latter one by mostly or exclusively rural character, They are abbreviated as BC and CC, if used and
