Westminster is an area in central London, part of the City of Westminster.
"Westminster" is often used as shorthand for the Palace of Westminster, which houses the Parliament of the United Kingdom and also, in a similar but contrary way, for the government (rather than legislature), which has many departments in the area (see Whitehall).
