Not sure as I really dont follow him.
It may be about events that happened years ago however, not necessarily the last few years.
Im trying to think of what may make this more shocking, or relevant to put on Dispatches and I think it would make more sense if there was a cover up.
This would have been in LP best interests at the time as they got the campaigning and attention. Now it may be released to try and influence voting for the next by election and general election (in favour of Tory)
Im not saying it's not true, but the timing is just very odd and why it had taken 3 years to investigate. That's virtually on the same level as Lucy Letby's criminal trial.
