(QHA) -

A Ukrainian presidential aide says President Petro Poroshenko will likely sign a decree to dissolve Ukrainian Parliament next week, RFE/RL reports.

Presidential adviser Oleh Medvedev told RFE/RL that a 30-day deadline to create a new coalition is about to expire and "the Ukrainian president has lawful grounds to dissolve the parliament." 

Medvedev did not specify the precise date. But in a tweet sent out on August 21, press secretary Svyatoslav Tseholko said Poroshenko could dissolve parliament as early as August 24. 

The UDAR and Svoboda parliamentary factions announced in parliament on July 24 that they were quitting the coalition. 

If deputies do not form a new coalition by the end of August, according to the constitution, the president can dissolve the parliament and announce early parliamentary elections.
