The limited time available in the House means there is a
time limit on most debates - many of which must end at
10 pm - so not everybody who wants to speak will get
the chance. When a debate on a Bill has no pre-set time
limit, opposing MPs can prolong the debate - and stop
the Bill progressing - by speaking for too long. This tactic
(known as 'filibustering') can be stopped by moving a
motion for 'closure' - which ends the debate so a vote can
take place.
Sometimes, when it anticipates delays, the Government draws up a
set timetable for the stages of a Bill. This is proposed in the form of a Timetable Motion (or 'guillotine'). The Government's majority will usually ensure this is passed without difficulty.
