How many senators are there in the United Kingdom?

Answer 1

None.

The British Parliament is made up of two Houses, The House of Commons and the House of Lords.

The House of Commons is the elected Members of Parliament, and the near equivalent of the US Senate is the House of Lords.

Members of the House of Lords were historically hereditary peers, but following recent reforms the members are mostly appointed. The Lords also includes Bishops and Archbishops of The Church of England and Senior Judges, both of which groups are also appointed and not elected.
