It's very clear to me. On August 17, the Minister of Finance was forced to resign because of his involvement in the scandal. On August 18, you prorogued Parliament, thereby putting an end to the work of the committees that were looking at the WE Charity scandal.
Who were you trying to save?
Once the Minister of Finance had resigned, who would have been next to end up in the hot seat and be forced to resign because of his involvement in the scandal?
