I've not seen any politicians coming out saying it's a coverup
Lammy and Abbott haven't said it but are getting close.
I do think the 600 figure is too high and that's leading to part of the problem about events and the dead/missing.
Some suggestions about the 79 figure being too low are that because Boris changed the way in which deaths are recorded in fires there is a discrepancy. Only people who die in a fire are now counted. So if you are rescued and then die in hospital you don't count. Or if you jump off a building and die that's suicide not death from a fire.
I don't think that holds up as one of those declared officially dead was from the 23rd floor and official cause of death is died of multiple injuries.
However this is the only official death in this manner too which also seems surprising as jumpers would be the most likely ones for their bodies to have survived in theory. This is one of the things Lammy has been getting upset about - lack of info relating to jumpers who were witnessed by residents. But without getting grusome there might be difficulties in identifying them too.
I can certainly see why there is frustration creeping into what Lammy is saying, and why he's saying it. It doesn't help that his friend was one of the first identified either as I think this puts him under certain extra pressures. But I also think what Lammy says is problematic in a way too - not that I blame him for it under the circumstances. I don't want to go in that much more, as I think it's unfair to him, as he is both personally and professionally caught up in this and that always creates problems.
The police do need to clarify a few things in the next couple of days. What Lammy was upset about mid week last week was more or less addressed in their last public statement on Friday (Lammy has asked why no documents had been seized but the Met stated this had happened on Fri), so perhaps his lead will result in a few more answers that people are looking for.
