Headline: “Britain refuses to apologize for the Balfour Promise, and the [PA] president will put it on trial”
     “Britain has refused to submit an apology for the Balfour Promise (i.e., Declaration) that was issued in 1917 and paved the way for the establishment of the State of Israel.
[PA] President Mahmoud Abbas demanded that Britain officially apologize to the Palestinian people for this promise in a speech that he gave before the UN General Assembly in September [2016], but Britain is intending to hold celebrations together with senior Israeli officials for the 100th anniversary of the Balfour Promise on Nov. 2 [2017].
Palestinian Ambassador to Britain Manuel Hassassian told [the official PA] radio [station] The Voice of Palestine that… ‘Steps will be taken to put Britain on trial for the Balfour Promise, and there are lawyers working on the matter in Britain. The position of the president is clear, and he will not retreat from it until Britain apologizes to the Palestinian people and recognizes the State of Palestine.’”

The Balfour Declaration of Nov. 2, 1917 was a letter from British Foreign Secretary Arthur Balfour to Baron Rothschild stating that “His Majesty's government views with favour the establishment in Palestine of a national home for the Jewish people” and is seen as the basis for later international commitments to establish the State of Israel.
