YANGON, May 31 (Xinhua) -- A number of ousted members of the former Myanmar ruling party, the Union Solidarity and Development Party (USDP), have called for an emergency conference in accordance with the party's basic principles, according to official reports Tuesday.

Under the party's principles, the party chairman must hold a conference demanded by 136 or 62.1 percent of the party's 219 central committee members elected in the 2012 party conference, said U Zaw Myint Pe, one of the expelled USDP members and former MP to the House of Nationalities (Upper House).

Meanwhile, the USDP Second Party Conference is scheduled to be held in August.

The sacked USDP members include U Shwe Mann, former Speaker of the Parliament and House of Representatives (Lower House) and several members of the current Legal Affairs and Special Cases Assessment Commission of the parliament, led by him.

In late April, purged senior members of the USDP issued an announcement calling for cooperation to work for the emergence of a democratic system aspired by the people with nobody staying above the law.

U Shwe Mann said despite dismissal of a party member is inter-party affair, it will indirectly impact in one way or another on interest of the state, urging for review of the party decision with understanding.

The USDP has removed 17 senior members, of whom 11 are members of the new parliament's Legal Affairs and Special Cases Assessment Commission.

The USDP made a major reshuffle of its leadership in August 2015 ahead of the year's Nov. 8 general election reforming its 47- member central executive committee (CEC) and retaining former president U Thein Sein as the party's chairman.

U Shwe Mann, who acted as the party chairman during U Thein Sein's assumption of presidency, was removed and replaced by U Htay Oo until U Thein Sein regained chairmanship after his presidency was handed to U Htin Kyaw on March 30.

The USDP lost to then opposition party, the National League for Democracy (NLD), led by Aung San Suu Kyi, in the 2015 general election, holding only 10 percent of the total of the parliamentary seats.
