Robert Mueller, the special counsel, has finished his report into whether Donald Trump's 2016 presidential campaign colluded with Russia.

A US justice department official said Mr Mueller, in his report, had not recommended any further criminal charges.

Rudy Giuliani, Mr Trump's lawyer, said he was "confident there is no finding of collusion by the president" and Mr Trump had done "nothing wrong".

The report was delivered, as is required, in hard copy form by Mr Mueller's team to the justice department following an investigation that lasted 675 days.

It will now be up to Bill Barr, the US attorney general, to decide how much of the report to release to Congress and the public.
