Paul Manafort, campaign chairman for Republican presidential nominee Donald Trump, has resigned just two months after taking the helm.
Mr Trump confirmed Mr Manafort’s departure in a statement.
‘I am very appreciative for his great work in helping to get us where we are today, and in particular his work guiding us through the delegate and convention process.
‘Paul is a true professional and I wish him the greatest success.’
The 67-year-old veteran political strategist has come under fire for his ties to Russian interests and former Ukrainian President Viktor Yanukovych.
