The organization said computer equipment and electronic devices at the addresses had been seized as part of its investigation into alleged data protection law violations.
Steve Eckersley, Director of Investigations at the Office of the Information Commissioner (ICO), said: “It is vital that all people, including departmental employees and members of the public who interact with them, have confidence in the protection of their personal data.
“In these circumstances, the ICO aims to respond quickly and effectively to investigate when there is a risk that other people have illegally obtained personal data.
“We have an ongoing investigation and will not comment further until it is completed. “
The investigation was launched in response to CCTV footage leaked from Mr Hancock’s office to The sun newspaper, which published them last month.
The footage shows the then-health secretary checking to make sure the hallway outside the office is clear before closing the door and kissing and kissing his taxpayer-funded advisor Gina Coladangelo.
CCTV footage was reportedly filmed on May 6, when English law banned social gatherings inside people from different households. The guidelines also urged people to stay two meters apart and avoid “face to face contact.”
Public reaction to the scandal led Mr Hancock to step down and be replaced by former Chancellor Sajid Javid as Health Secretary.
It has been reported that both Mr Hancock and Ms Coladangelo have left the family home.
Mr. Hancock has three children with his wife Martha, an oestopath. Ms Coladangelo has three children with her husband Oliver Tress, owner of street retailer Oliver Bonas – where she had worked as director of marketing and communications.
Ms Coladangelo, previously director of lobbying firm Luther Pendragon, had met the Tory MP for West Suffolk at the University of Oxford where they became close friends around a shared passion for student radio.
In September last year she was given a £ 15,000 a year post as a non-executive director in the Department of Health and Social Affairs. There is no public record of the appointment, which was made during the Covid-19 pandemic, but it is listed on her LinkedIn page.
Mr Hancock has been accused of cronyism on several occasions because of his personal connections to companies and individuals who won contracts with the NHS during the pandemic.
Earlier this year, the High Court ruled that Mr Hancock acted illegally by awarding contracts to companies without tendering and then failing to publish their contact details.
Mr Hancock’s alleged use of a personal email account to conduct government business has raised transparency concerns.
