High representative Josep Borrell was speaking after President Donald Trump unveiled a "last opportunity" for the Palestinians to sign up to a plan drawn up by US officials.

"The European Union will study and assess the proposals put forward," Borrell said.

But he added: "This will be done on the basis of the EU's established position and its firm and united commitment to a negotiated and viable two-state solution that takes into account the legitimate aspirations of both the Palestinians and the Israelis, respecting all relevant UN resolutions and internationally agreed parameters."
