What caused the Grenfell Tower fire?

We do not yet know how horrific the death toll will be, but questions are already being asked about the Grenfell Tower fire. As there should be – a disaster of this scale should never have happened.

There are allegations that the cladding added in a recent renovation was flammable, that the renovation reduced the number of fire escapes at the lower levels (see plans here), that some residents had obstructed access by dumping rubbish, and that bad evacuation advice was given to residents. Hopefully there will be a full investigation, and enough policy changes to stop something like this from happening again.
