Order, please. It is the rule and the standard practice of the House that once the Speaker begins to put the question, then at that moment no member is allowed to take their seat and then have their vote counted. As I saw events, the Minister of National Defence sat down before I began to put the question, and so I do not think there is anything untoward there.
In the House of Commons on February 8th, 2012. See this statement in context.
