Two people suspected of illegally leaking CCTV footage of Matt Hancock and his aide Gina Coladangelo will not be prosecuted due to insufficient evidence, the information watchdog said.
The footage leaked to the Sun last year, showing Mr Hancock kissing Ms Coladangelo in his departmental office, led to him resigning as health secretary for breaking social distancing rules that were in place at the time.
It also prompted a criminal investigation by the Information Commissioner’s Office (ICO).
The ICO said: “Forensic analysis revealed that the leaked images were most likely obtained by someone recording the CCTV footage screens with a mobile phone.
“Six phones retrieved during the execution of search warrants did not contain the relevant CCTV footage.
“After taking legal advice, the ICO concluded that there was insufficient evidence to charge anyone with criminal offences under the Data Protection Act 2018.
“The ICO has therefore closed its criminal investigation.”
