What is the message for two ex PM’s

Is there any message for two ex PM Nawaz Sharif and Shahbaz Sharif from concern quarters through Governor Sindh Kamran Tessori . Officially released pictures from London home of PML N supremo is very much debating in pakistani politics. Independent circles indicated that meeting might be an political alliance between MQM and PMLN in coming election same like experienced in 90s period when both parties were the fully backed by the then military establishment against the Benazir Bhutto. Howver that both alliance were breaked on bad experience and MQM faced two major operation against party.
Political observer believed that the meeting of Tissori with two ex PMs was just a social gathering as the Shahbaz Sharif is in direct relations with establishment.
