Nato chief Mark Rutte has been forced to backtrack on an embarrassing remark - where he apparently called US president Donald Trump 'daddy.'

During a meeting of the defence bloc in the Hague yesterday, Rutte and Trump met following the US president's crass comment on the Iran-Israel war.

It was there that the US President he said: 'We basically have two countries that have been fighting so long and so hard that they don't know what the f*** they're doing.'

Rutte said on Wednesday that 'Daddy has to use strong language' to get Israel and Iran to sort things out, to which Trump agreed.

'You have to use strong language. Every once in a while you have to use a certain word,' the president said.
