Please describe British democracy and government and compare it to Turkey's system.
This is a big question because there are so many different aspects of government that could be compared. I will look simply at the overall structure of the two countries' systems.
Both Turkey and Britain are parliamentary democracies. In both, there is an elected parliament that has the power to make legislation. In both countries, essentially all adults have the right to vote. In both cases, the executive power is held by a Prime Minister. Both countries have a judicial system that is, for the most part, independent of the other two branches of the government.
So, in terms of their structure, the governmental systems of Great Britain and Turkey are really quite similar.
One thing I should mention here is that in Turkey, unlike in Britain, the military is a factor in politics. This is true even though Turkey's military does not officially have a role in government. However, it has carried out coups d'etat in recent years and continues to try to influence politics in Turkey today (usually pushing for a strictly secular society).
