The event is due to be attended by Prime Minister Theresa May and her Israeli counterpart Benjamin Netanyahu.
Jeremy Corbyn rejected an invitation to attend the dinner, which is being held to mark 100 years since the declaration that helped paved the way for the creation of a Jewish state.
Corbyn has asked Emily Thornberry, the shadow foreign secretary, to attend the dinner in his place, The Sunday Times reported.
A spokesman for Corbyn confirmed to Arab News that he would not attend but that Thornberry would go in his place.
The Balfour Declaration, signed on Nov. 2, 1917, pledged the UK government’s support for a Jewish “national home” in Palestine.
Mark Regev, Israel’s ambassador to London, told The Sunday Times that those who oppose the declaration are “extremists” who reject Israel’s right to exist and could be viewed on a par with terrorist groups such as Hamas.
Regev said a “vocal minority” of British students and academics are intent upon the destruction of Israel.
Yet an Arab News/YouGov poll conducted in August found that only a minority of Brits believe the Balfour Declaration is something to be proud of, with the majority in favor of the UK recognizing Palestine as a state.
The UK government has refused to apologize for the Balfour Declaration, reaffirming instead that it was “proud of its role” in creating the State of Israel.
The Palestinian ambassador to the UK vehemently disagrees with that stance, telling Arab News this month that “the displacement of the Palestinians is a result of that document.”
Chris Doyle, director of the Council for Arab-British Understanding, questioned why government ministers are celebrating Balfour but “are doing nothing to acknowledge the devastating impact it has had on Palestinians.”
He told Arab News that the celebrations over the declaration will “inflame and anger.”
Doyle added: “Jeremy Corbyn is missing the Balfour event but he should be clear about why and not be silent. It should be a strong message that Balfour cannot be celebrated until Palestinian aspirations and rights are met as well.”
