Donald Trump's former adviser Roger Stone has been found guilty on all seven counts of obstruction, witness tampering and lying to Congress.

The self-proclaimed "dirty trickster" was found guilty of the offences by a jury in Washington on Friday.

A long-time Republican operative and friend of Mr Trump's, Stone was an adviser to the then-candidate during his 2016 presidential election campaign.He is the sixth Trump aide or adviser to be convicted of charges brought as part of special counsel Robert Mueller's investigation into Russian interference of the election.

His trial in a federal court arose from that investigation and damaging WikiLeaks emails, hacked by Russia, about then-Democratic presidential nominee Hillary Clinton.
