The anti-government alliance will observe a countrywide "black day" on July 25 against alleged rigging in the July 25, 2018, general elections, PPP leader Waqar Mehdi announced in a press conference on Tuesday at Bilawal House, Karachi after a multiparty meeting.

The opposition parties in the National Assembly also decided to hold a general convention on the same day outside the Mausoleum of Quaid-i-Azam Mohammad Ali Jinnah. Central leaders of the opposition parties will address the event. Conventions will also be held in other provincial capitals.

The decision comes at a time when the country's political atmosphere is already charged and the tussle between the ruling and opposition parties has reached the next level. Opposition parties have submitted a no-confidence resolution against the Senate chairman [who enjoys the support of the ruling party], while the ruling PTI has taken the same step against the deputy chairman of the Senate who belongs to the PPP.

The PPP leader said that inflation, joblessness and poverty have increased immensely since the incumbent "selected" government was "imposed". He added that the July 25 general convention would become a milestone in the country's politics.
