Indeed, even though the Duma Speaker is technically on an equal level with that position in the Kremlin, the duties and powers are vastly different. If the Kremlin is strong enough, then the Duma Speaker essentially has no say in the matter.
This Duma session seems more active than usual, but that is the result of Wang Ye painstakingly managing the situation, not indicative that the Duma could always exercise such strong power before or after this.
But let's not forget, Russia is a classic presidential strong-power system!
So Wang Ye also doesn't want someone who is either too strong or has the backing of powerful forces to take on this role; otherwise, there will inevitably be power struggles between the Duma and the Kremlin.
The two discussed for a while, and Rossiyana, still unwilling to accept defeat, hinted at seeking Wang Ye's help.
