The Democratic Society Party (DTP), which will formally cease to exist when the court ruling is published in the official gazette, will convene Monday "to reach a conclusion on how and when the resignation decision will be implemented," the statement said.

The meeting will be held in Diyarbakir, the largest city of the mainly Kurdish southeast, with the participation of local Kurdish activists, it said.

The constitutional court outlawed the DTP Friday on grounds it was linked to the Kurdistan Workers' Party, which has led a bloody 25-year insurgency in the southeast and is listed as a terrorist group by Ankara and much of the international community.

DTP co-chair Ahmet Turk said Saturday party lawmakers had "pulled out from parliament" and would boycott all work there.

In a decision made before the court verdict, the DTP had said its lawmakers would resign from their parliamentary seats if the party was disbanded.

If DTP lawmakers step down and their resignations are approved by parliament as the law requires, the move may raise the prospect of a by-election.

The DTP was left with 19 members in the 550-seat legislature after two deputies, including Turk, were stripped of their seats as part of Friday's verdict.

The party has come under pressure to keep its members in parliament to demonstrate commitment to a political solution to the Kurdish conflict.

The remaining 19 deputies can sit as independents or regroup under the banner of a new party.

The possibility of forming a new party "is not on our agenda," Sunday's statement said.
