PPP secretary general Nayyar Bukhari, at his residence, was visited by a PML-N delegation, under the leadership of Raja Zafarul Haq. The PML-N delegation forwarded Nawaz’s message for the PPP’s senior leadership.

According to scources, the PPP leader was told by the PML-N delegation that if PPP joins the opposition alliance, the PTI government would face a tough time in and out of parliament. The PML-N has also offered joint candidates in the forthcoming by-election.

Sources have said that the PML-N President Shehbaz Sharif will arrive in Islamabad tomorrow and it is expected that in days to come he will lead party's delegation in meetings with PPP leaders.
