An SFO spokesperson said: “In line with long established practice to avoid prejudice to law enforcement activity, we can neither confirm nor deny any investigation into this matter.”
Len McCluskey, Sharon Graham’s predecessor as general secretary, had championed the project and said in 2021 that it was “a fantastic investment”.
He later tweeted the internal inquiry was “sensible and will answer any questions”.
A lawyer for Mr McCluskey has told the that due to the ongoing investigation it would be inappropriate for him to comment.
The Birmingham project was intended to be an investment for Unite as well as saving the union money with hotel and conference costs.
Construction was completed in 2020 and development includes the four-star, 195-bedroom Aloft Birmingham Eastside hotel and a 1,000-person capacity conference centre, as well as Unite’s regional offices.
Employment tribunal documents reveal the union believes its ruling executive council had been misled as to the true value of the project.
In 2022 South Wales Police searched the union’s London headquarters as part of a separate bribery, money-laundering and fraud investigation.
The force has told the that the investigation is ongoing.
A Unite spokesperson said: “It is important to note that Sharon Graham has had to endure repeated attacks by those with much to lose since she launched these inquiries, from both inside and outside the union.
“These have been sickening and horrendous but she has remained determined to get to the truth.
“We are also pursuing legal claims to recover money lost to the union and the general secretary has put safeguards in place to ensure that such things can never happen again.”
