"The old visa has expired, and he applied for a new one. But the processing time is currently longer than usual," the source said, adding that due to this reason Abramovich could not enter the United Kingdom at the moment.
The UK Home Office has refused to provide any comments on the issue.
On Sunday, the Bell news website, citing sources from the businessman’s inner circle, reported that Abramovich’s UK investor visa had expired more than three weeks ago, but the billionaire hadn't received a new visa.
On March 27, UK Prime Minister Theresa May said the UK Home Office was undertaking the review of the Tier 1 Investor visas to ensure that nobody can use this program to circumvent residency restrictions.
The statement was made amid deteriorating relations between the United Kingdom and Russia after London accused Moscow of involvement in the attempted murder of former Russian spy Sergei Skripal and his daughter Yulia with a nerve agent in the UK city of Salisbury. Russia has refuted the accusations and demanded an independent investigation into the incident.
