ISLAMABAD (Reuters) — Half a dozen major Pakistani opposition parties have joined forces to denounce the military which they accuse of meddling in politics and rigging the 2018 elections to bring Prime Minister Imran Khan to power.

The six parties and some smaller groups signed a statement late on Sunday announcing the creation of the Pakistan Democratic Movement to begin nationwide agitation, possibly culminating in a January march on the capital, Islamabad.

“The (military) establishment should stop every kind of interference in politics forthwith,” said the statement, which accuses Khan of failing on multiple counts, from the economy to foreign policy.

The alliance did not give a schedule for the street protests except for announcing the march on the capital if the government did not stop victimising political opponents. It demanded electoral reform to ensure “no role for the armed forces and [intelligence] agencies”.

The next general election is scheduled for 2023.
