The constitutional experts belonging to the Pakistan Democratic Movement (PDM) have once again sat together to deliberate on an in-house change in Punjab and table a no-trust motion against the provincial assembly's speaker before removing Chief Minister Chaudhry Pervez Elahi.

Completing the numbers game of 186 is inevitable for this process that seems to be next to impossible, the constitutional experts have opined.

Sources told that during the meeting between Prime Minister Shehbaz Sharif and PML-N supremo Nawaz Sharif in London, important consultations were made on the issue of an in-house change in the province.

The two leaders agreed on evolving a strategy immediately in consultation with PDM leaders.

On the other hand, the PDM leaders have proposed tabling a vote of no trust motion against the PA speaker before removing the CM. Consultations have been started in this respect.

The modus operandi would be decided after the arrival of former president Asif Ali Zardari in Lahore.

It is pertinent to mention here that PTI Chairman Imran Khan has claimed that the opposition parties are conspiring to topple his government Punjab.
