The government of the day runs the UK. The government comprises the Prime Minister and the elected members of Parliament in the lower house, and the upper house. We elect those MPs- those of us who vote- as our representatives, so in effect we run the country. John Bercow, a Conservative MP, has been elected by MPs to be, in effect, chairman of the house. He makes sure MPs abide by the rules of parliament. We have a parliamentary democracy, of which Churchill said: “..it has been said that Democracy is the worst form of government except for all those others that have been tried from time to time.”
