An unwieldy coalition of lawmakers trying to implement Nepal’s first democratic constitution is finding common cause with protesting minority groups, isolating Prime Minister KP Sharma Oli and increasing the risk his government could fall this spring.

Oli, of the leftist Communist Party of Nepal (Unified Marxist-Leninist), promised to resolve simmering tensions in the southern plains and lift a blockade of the Indian border when he was voted in to power almost four months ago.

Yet sporadic violence, in which more than 50 people have died since August, continues in the Himalayan nation with police shooting dead three demonstrators last month.

Protest leaders say the heavy-handed police tactics show the government is not sincere about finding a solution, while in Kathmandu residents have to choose between queuing for hours for fuel and gas and paying exorbitant prices on the black market.
