Donald Trump’s former campaign chairman Paul Manafort has been found guilty on tax fraud charges in Virginia federal court, in a resounding victory for special counsel Robert Mueller and his team in the first trial arising from their investigation.

Manafort, 69, was convicted on five counts of tax fraud, two counts of bank fraud and one count of failure to report a foreign bank account. The charges carry a maximum sentence of decades in prison. He avoided conviction on some charges however, with the jury saying it could not reach a consensus on 10 out of 18 total counts.

Manafort faces additional charges in a separate case, to convene in Washington DC in September.
