The following occurred on private property, no civil servants involved and not illegal.
There was an incident which the other side found funny and they decided to record me without my knowledge. When I find this out, I ask them to delete the video and photos, which they said they would. At this point, I have withdrawn my consent.
I later see their phone and they haven't removed the footage.
Which act covers this, specifically a section so I can look it up on legislation.gov.uk?
