British opposition figures are urging Prime Minister Theresa May to recognize a Palestinian state as she prepares to host Israel's Benjamin Netanyahu to mark the centenary of the Balfour declaration on Thursday evening.

Axar.az reports citing AA that Emily Thornberry, shadow foreign secretary for the main opposition Labour Party, thinks the centenary could be a good time for the U.K. to officially recognize Palestine.

"It seems to me that it was right to be a true friend of either side; you need to recognize the legitimate concerns of both parties," Thornberry told Anadolu Agency.

"One of the things about Balfour that strikes me is that it … reinforces to me a very important reminder that when British politicians clearly state their policies on the Middle East that these words can make a difference," she said.

Thornberry will represent Labour at a celebratory dinner to be hosted by Lord Jacob Rothschild and Roderick Balfour -- the representatives of Rothschild and Balfour families -- after party leader Jeremy Corbyn’s previous announcement that he would not attend.

"We have a shared duty to look to the future. Britain has a duty as well. We need to look forward and the only way to forward seems to me is for there to be a viable, secure state of Israel and alongside the viable, secure state of Palestine," Thornberry said.

"The Conservative government say they will recognize a Palestinian state but doesn’t say when they will do it," she added.

"And we say, do it on the 100th anniversary of the Balfour Declaration. We have to recognize Palestine. If this government is not prepared to recognize a Palestinian state, the next Labour government will.

"What is important is that we fulfil the whole promise and we have a role in this... We have a responsibility to do everything that we can in order to ensure that there is proper two-state solution."

The Labour shadow minister is not the only lawmaker who thinks now is the time to recognize a Palestinian state.

Tom Brake, the Liberal Democrat lawmaker for Carshalton and Wallington, says Palestinians are entitled to a state such as much as Israelis.

Speaking to Anadolu Agency, Brake said recognizing a Palestinian state “is the right thing to do in the circumstances. The Palestinians are entitled to a state in the way that the Israelis are entitled to a state."

"At the moment I am afraid the government appear to be linking it to other factors in terms of progress on the peace process, issues to do with Hamas, but there is a fundamental principle and the fundamental principle is that the Palestinians are entitled to a state,” he said.

“And that has got to be the starting point and that is what collectively and cross party we have to try and get the government to accept," he added.

Noting that the House of Commons “has already voted to recognize Palestine,” Brake said: “We might be able to secure that [recognition] because the government does not command a large enough majority to oppose such a measure."

Brake said the Palestinians had been let down and for them “there is nothing to celebrate.”

“We didn’t deliver on half of the promises that we have made a hundred years ago; that’s why we have to keep the focus on that, try to ensure that we use the historical connection we have to deliver for the Palestinian people a hundred years after we first said we would."
