Hamas put an end to coalition talks after failing to reach agreement with other parties and said it would form a government by itself, a move likely to deepen the international isolation of the Palestinian Authority. Hamas said it planned to present its cabinet to the Palestinian parliament for approval on Monday. However, it first needs approval from the Palestinian president, Mahmoud Abbas, who will meet Hamas leaders over the weekend.Abbas is expected to ask Hamas to rework its government programme, an official close to Abbas said on condition of anonymity, because he is not authorised to reveal the content of the negotiations. The official also said Abbas would tell Hamas its hardline platform was too vague and thus unacceptable.
