The sentencing hearing is scheduled for 3.30pm (20.30 GMT)
Manafort was convicted after prosecutors accused him of hiding from the US government millions of dollars he earned as a consultant for Ukraine’s former pro-Russia government.
After pro-Kremlin Ukrainian President Viktor Yanukovych’s ouster, prosecutors said, Manafort lied to banks to secure loans and maintain an opulent lifestyle with luxurious homes, designer suits and even a $15,000 ostrich-skin jacket.
Manafort faces sentencing in a separate case in Washington on March 13 on two conspiracy charges to which he pleaded guilty last September.
While he faces a statutory maximum of 10 years in the Washington case, US District Judge Amy Berman Jackson potentially could stack that on top of whatever prison time Judge Ellis imposes in Virginia, rather than allowing the sentences to run concurrently.
Judge Jackson on February 13 ruled that Manafort had breached his agreement to cooperate with Mueller’s office by lying to prosecutors about three matters pertinent to the Russia probe including his interactions with a business partner they have said has ties to Russian intelligence.
Judge Jackson’s ruling could impact the severity of his sentence in both cases.
Special Counsel Mueller is preparing to submit to US Attorney General William Barr a report on his investigation into whether President Trump’s campaign conspired with Russia and whether the President has unlawfully sought to obstruct the probe.
President Trump has denied collusion and obstruction.
Russia has denied election interference.
Manafort is the only one of the 34 people and three companies charged by Special Counsel Mueller to have gone to trial.
Several others including former campaign aides Rick Gates and George Papadopoulos, former national security adviser Michael Flynn and former Trump personal lawyer Michael Cohen have pleaded guilty, while longtime Trump adviser Roger Stone has pleaded not guilty.
Gates, a key witness against Manafort, has yet to be sentenced due to his ongoing cooperation with prosecutors.
Special Counsel Mueller’s charges led to the stunning downfall of Manafort, a prominent figure in Republican Party circles for decades who also worked as a consultant to such international figures as former Angolan rebel leader Jonas Savimbi, former Philippine President Ferdinand Marcos and Yanukovych.
Defence lawyers have asked Judge Ellis to sentence Manafort to between 4¼ and 5¼ years in prison.
They are expected to tell the judge Manafort is remorseful and that the sentencing guidelines cited by prosecutors call for a prison term disproportionate to the offences he committed.
