KIEV (Reuters) - A Ukrainian opposition lawmaker began a hunger strike on Monday, accusing central government of inaction in allowing trash to pile up in the picturesque western city of Lviv, the power-base of his Samopomich (Self-Reliance) party.

Party leader and Lviv mayor Andriy Sadovyi accuses Kiev of blocking efforts to reroute rubbish from the city’s overfilled landfills to sites outside the region in an effort to discredit Samopomich. The party quit the ruling coalition in early 2016.

Some analysts say the row is early jockeying ahead of parliamentary and presidential elections due in 2019.

President Petro Poroshenko and the government say Sadovyi’s office is to blame for the problem in the city known for its baroque churches and cobbled squares; but they say they are willing to help.

Parliamentary deputy Oleh Berezyuk, the Samopomich faction leader in parliament, launched his hunger strike on the steps of the presidential administration building in Kiev.

“As a person, a doctor and a member of parliament I have taken the extraordinary decision to go on hunger strike in support of Lviv citizens and in protest at the high-handedness of the central authorities,” Ukrainian media quoted him as saying in a faction leaders’ meeting.

He did not say how long the strike would last.

Lviv council has asked for a state of emergency to be declared to remove over 8,500 tonnes of accumulated trash.

On Monday Prime Minister Volodymyr Groysman said the government was prepared to consider setting aside 50 million hryvnias ($1.9 million) for landfill construction in the Lviv region.

During a conference call with regional authorities he also said: “I want to ask the whole country, if Lviv Mayor Andriy Sadovyi happens to turn to you for help, I beg you, help if you can,” his press service quoted him as saying.
