Francois Hollande has said he finds Donald Trump's "excesses" sickening, claimed that democracy is at stake in the 2016 US election and stated a victory for the Republican could make politics more conservative around the world.

The French president is the latest high profile politician to condemn Mr Trump after the billionaire businessman attacked the parents of a Muslim American soldier killed in Iraq.

"His excesses make you want to retch, even in the United States, especially when - as was Donald Trump's case - he speaks ill of a soldier, of the memory of a soldier," Mr Hollande said.
