[1] The ward covers the eponymous street market and the surrounding area of Lisson Grove, to the north of the Edgware Road.
The ward returns three councillors to Westminster City Council, with an election every four years.
Since the ward was created for the formation of the council in 1965, it has usually elected Labour councillors, with most results indicating a safe seat for the party.
The sole occasion another party represented the ward was following the by-election of 24 July 2008, when a seat was won by a Conservative candidate for the first and only time to date, beating Labour's candidate Dave Rowntree, the drummer from the band Blur.
Previous councillors elected for the area include the Dowager Countess of Lucan, barrister and current QC Gavin Millar, and subsequent London Assembly AM Murad Qureshi.
