Also just to add that I've just noticed this lady's council place is in Southwark, which is where me and my friend lived. Out of my friend's landlord's in Elephant and Castle:
One was a sham landlord who didn't even provide heating and housed undocumented people in one of the flats (probably charging them insane rent). He tried to charge my friend for electricity and water for the whole building. I investigated him and turned out he was a sri-lanken national builder convicted of using slave labour on one of his sites.
One was a Nigerian national, London bus driver who was housed in one of Elephant & Catle's redevelopments - he sublet 3 out of 4 of the bedrooms and was staying somewhere else most of the time and frequently abroad,
The third was an English guy in a 3 bed maisonnette flat - the one that burnt down. He was also hardly there so presumabely staying somewhere else.
These were all single men in family-sized properties which they were subletting, while homeless local women and children were stuck in bedsits for years on end. It infuriated me so each time my friend moved out I reported them. Don't know if anything was done though and I suspect not.
By the way I am very liberal person and my son is mixed race. I'm heavily in favour of multi-culturalism and I love London's vibrancy - I've commented on nationality but it's not about that for me, it's more that I think the biggest issue is the system is so lax and lets people take advantage of it. Absolutely people should be assessed on a regular basis and I don't believe the policy of council houses for life is a good one as there is a shortage which means families are housed in temporary or private housing which is insecure for them and expensive for the tax payer.
