Jerusalem  - A two-state solution remains the goal in efforts to end the Israeli-Palestinian conflict, Israel's opposition leader Tzipi Livni said Sunday, ahead of a visit to the United States, Israeli media reports said.

Livni was due to depart Saturday for Washington to attend a three- day meeting of the US' pro-Israel lobby and hold talks with Secretary of State Hillary Rodham Clinton and Vice President Joe Biden.

Livni said she wanted to address in particular the subjects of Iran's threats against Israel, the militant pro-Iranian Hezbollah group, as well as the radical Islamist Palestinian Hamas movement in her speech at the American Israel Public Affairs Committee (AIPAC) policy conference.

There was no disagreement on these issues between her centrist Kadima party and the new right-wing government of Prime Minister Benjamin Netanyahu of the Likud party, she said.

On the question of the Palestinians, however, there was no agreement, she noted. "We want a two-state solution because the other options are bad for Israel," Livni said, adding she did not however want to present the Netanyahu government as illegitimate.

Israeli President Shimon Peres was also due to address the AIPAC conference on Monday. He would also hold talks with US President Barack Obama in Washington.

Obama has invited both Netanyahu and Palestinian President Mahmoud Abbas for talks later this month. In addition, the US President is expected to travel to the Middle East in mid-June.
