I can see details of upcoming business in the House of Commons at http://calendar.parliament.uk/, but how does this translate to votes/divisions that subsequently take place?
Is there a record of planned votes in the Commons, or do votes occur spontaneously as a result of debate? I had presumed that for a Whip to be effective, there would need to be clearly defined details of upcoming scheduled votes. If votes are scheduled and predictable, is there a definitive http://www.parliament.uk source for this information?
