The House of Commons, where I worked for two summers.  The MP I worked for might be the one on the very back bench leaning forward at the upper left.  Conservatives sit on the left side, Labour on the right (when this was taken, now they have switched sides as Labour is now in control of the Government).  The red lines on the floor are exactly two sword legths apart, and members cannot cross them whilst speaking.  There are still loops in the cloak room for hanging your sword before entering the chamber.   The Speaker sits in the big chair in the middle and regulates the debate.  The Speaker is a member, who must stand for election (though rarely does anyone run against her (or him) but is non-partisan for the duration of her term.  The gold mace at the end of the table signifies that the House is in regular session.  When the House goes into a Committe of the Whole, the mace is lowered under the table (where there are hooks for it).

The two wooden boxes the "Dispatch Boxes" are where the ministers stand to answer questions from the opposition and their own party during question time, and where ministers stand to make reports.  The ministers and shadow ministers (opposition) sit on the front benches by the table.  The leaders of the smaller parties sit on the front benches away from the table.  The "back benchers" are the rank and file members of the House.

My MP, Bowen Wells, has the rare distinction of chairing a committee even though his party is out of power.
