The allies will support the government come what may, on the other hand there is a lot of ego in both pti and pmln to launch a combined protest movement against the government. I wouldnt want any protest movement to be hijacked by the khaki people as well. Pti is ready for the elections or not I believe that the elections should be held by the end of this year at the most, October/November ideally. The government could announce the elections after the budget in may, I think the opposition should wait for that but if nothing happens then they can go ahead with their protest movement.
I agree that mass protests by pmln will attract a lot of people at this stage but we will have to see what actually they want to achieve.
