Plaid Cymru’s four MPs have backed calls for a sporting and economic boycott of Israel over the war in Gaza.
The group’s Westminster group backed a motion at the group’s conference calling Israel an “apartheid state” and accusing it of “genocide, ethnic cleansing and war crimes”.
Plaid members will decide whether the group should approve the calls when they meet in Cardiff later.
The Palestinian ambassador to the UK, Husam Zomlot, will also address the conference on Saturday afternoon.
In an interview with the BBC, party leader Rhun ap Iorwerth expressed differences of opinion on this issue, refusing to confirm whether he approves of the proposal.
The motion proposed by members of the group in Ceredigion condemns “in the strongest terms” the killing of tens of thousands of Palestinians, including more than 10,000 children, by the Israeli state.
It condemns “the violence perpetrated by Hamas against innocent people in Israel” but says “the continued repressive apartheid regime maintained by the Israeli government makes the two-state solution less likely to bring about a just peace”.
The proposal says the UK government should “expel the Israeli ambassador”, ban arms sales to Israel, and that all Plaid members should support an “economic and cultural boycott”.
That would include Wales’ national sports teams boycotting the country.
It also says councils must divest from companies that “support the apartheid Israeli regime”.
Ap Iorwerth said Israel had violated international law but refused to support the boycott proposals himself.
“People will take different positions on things like the boycott,” he said.
“That attack last year was shocking, and we condemn it. We need to see the release of the surviving hostages, but we also need to declare the state of Israel.”
About 1,200 people – most of them Israeli citizens – were killed in a Hamas attack on October 7.
Since then, about 42,000 people have been killed as part of Israel’s crackdown on Gaza, according to the Hamas-run health ministry.
Plaid’s motion cites Amnesty International, which in 2022 said Israel’s laws, policies and practices against Palestinians in Israel and the occupied territories amounted to apartheid.
It said it maintained “the established regime of oppression and domination of the Palestinian people for the benefit of Jewish Israelis”.
At the time, Israel’s Ministry of Foreign Affairs accused Amnesty of recycling “lies, inconsistencies, and baseless assertions from well-known anti-Israel organizations”.
The Palestinians have blamed Israel for the massacre in Gaza, which the country has denied.
UN special rapporteur on human rights Francesa Albanese said she believed Israel had committed “acts of genocide”, while the International Court of Justice ruled in January that the country must “take all measures to prevent acts of genocide”.
Luke Fletcher, Plaid Cymru Senedd member for South Wales West, told BBC Radio Wales Breakfast that he wanted to hear a debate on the proposal on Saturday.
He said he was not clear about the boycott issue.
But he added: “I think it’s very clear that it’s been a year now that we want a ceasefire, since the conflict started, it comes to the point where you have to start, I think, sanctions in order to reach the goal we all have which is peace in the region.”
At the conference, Fletcher will set out the party’s plans to boost the Welsh economy by establishing a new national development agency and a reform bank, vowing to change business values ​​for small and medium-sized businesses.
