Donald Trump has appeared to endorse far-Right leader Marine Le Pen days before the French election following the murder of a policeman in a terrorist attack in Paris.

The US president tweeted early on Friday morning that "France will not take much more of this".

He added: "Will have a big effect on the presidential election" - seeming to suggest that it will push voters towards Ms Le Pen.

Ms Le Pen on Friday morning called for all terrorist suspects to be expelled from France.
