National Assembly vice-chair Urmila Aryal resigned from the post on Thursday on the heels of the changed political situation in the country.

She is believed to have stepped down from the position to pave the way for the election of a lawmaker from one of the other ruling coalition partners to the position.

A Maoist leader Narayan Dahal was elected chair of the upper house earlier this month. A common candidate of the five-party ruling coalition, Dahal got elected to the post defeating Yuvaraj Sharma of the main opposition Nepali Congress.

The newly formed four-party ruling coalition on March 4 had agreed to elect a Maoist candidate to the top post of upper house chair that went vacant after Ganesh Timilsena completed his six-year tenure as the Assembly chair on March 3.

In the eight-point agreement, the four parties had stated that they would elect a CPN-UML lawmaker as vice-chair of the Assembly.

The agreement was signed by Maoist Centre chair and Prime Minister Pushpa Kamal Dahal, UML chair KP Sharma Oli, Rastriya Swatantra Party chair Rabi Lamichhane and Janata Samajwadi Party chief Upendra Yadav.

But later on March 12, CPN (Unified Socialist) joined the ruling coalition and the five-party alliance reached another agreement that didn't mention anything about the election of the vice-chair so it is assumed that the Unified Socialist might have been offered the position.

Aryal got elected to the post in February last year. A long-time UML leader Aryal quit the party and joined the CPN (Maoist Centre) over a decade ago.
