"Those who signed this document are declaring an end to the escalation of the conflict and are taking on commitments to carry out a reconciliation plan on the basis of compromise, democracy and national interests," the document said.
Oleksandr Moroz proposed cancelling the presidential order to disband parliament and call early elections, which triggered a new wave of tensions in the ex-Soviet state April 2, or suspending it until a Constitutional Court decision on its legality, as well as cancelling all resolutions adopted by the defiant Supreme Rada and the Cabinet since then.
The plan, drafted by the majority coalition loyal to Prime Minister Viktor Yanukovych, proposes delaying the election date from May 27 to the summer or fall in the event of a positive court ruling on President Viktor Yushchenko's decree.
If the court, due to make a decision by April 27, overturns the decree, the coalition said it was prepared to amend election legislation, review parliamentary procedures to prevent lawmakers from switching factions, and make changes to the law on the Cabinet, restricting presidential powers.
The plan also envisions a host of other legislative moves to appease the opposition, democratize the judicial system and legalize a power-sharing deal between the political factions in August, when Yanukovych returned as premier after being defeated by Yushchenko in the 2004 contested presidential race.
Yushchenko earlier said he could suspend his decree, triggered by the defection of 11 pro-presidential lawmakers to the parliamentary majority and designed to prevent Yanukovych from "usurping power."
Moroz also urged the parties involved to heed appeals for a political solution from the Parliamentary Assembly of the Council of Europe (PACE) last week and called on supporters of both camps to end their rallies in Kiev.
Thousands of demonstrators have been besieging the Constitutional Court building pending its decision and rallying in central squares in the capital, either protesting against early polls or demanding them.
The latter have been encouraged by Yulia Tymoshenko, Yushchenko's fierce ally in the 2004 mass protests that brought him to power.
Over 150 lawmakers from the bloc led by Tymoshenko, a former premier, and pro-presidential Our Ukraine tendered their resignation to Yushchenko last week to make the legislature unable to pass decisions.
"All our members of parliament have offered their resignation to the sole legitimate person in the country, the president," the Yulia Tymoshenko Bloc said Thursday.
