A politics fellow has said the magnitude of the claims facing US president Donald Trump "are so great we need to know they aren't true."
Buzzfeed published a document containing unverified claims the Russians are compiling a dossier of damaging information about the President-elect.
The memo - compiled by a former British intelligence officer - was reportedly included in a report presented to Mr Trump and current President Barack Obama.
Mr Trump has vehemently denied the claims that a dossier exist. However Dr. Brian Klaas, a political fellow at the London School of Economics, said it is vital that the allegations are investigated.
"This is not the same as fake news," he told Julia Hartley-Brewer, "This is elevated to a level where intelligence is investigating.
"The magnitude of the claims are so great we need to be sure they are not true, because we need to know the President of the United States isn't being blackmailed by a foreign power.
“If any of it is true, it is deeply troubling because it’ll be unprecedented to have someone compromised before they take office.
"Now the allegations are in the public eye, there’ll be much more weight behind it. Let’s treat this with caution, but we need to get to the bottom of this, because in nine days, this man will take office."
