Madam Speaker, the prorogation that took place last summer was easily justified in regard to the previous throne speech and the necessity to introduce a new throne speech, which was done on September 23. All one needs to do is just read the document to get a better appreciation as to why prorogation was important, keeping in mind that even through the prorogation, we might have lost maybe two days of debate at best.
