Unless it's happening in Africa, neither Harry or MM are interested.
I don't know about now, but when this story first started, five people were genuinely homeless and were from Windsor. One Woman had, had a marriage breakdown, couldn't get accommodated by the Council and drifted into Homelessness. She stayed in Windsor because it was safer than other places, particularly for Homeless Women. She also had some support, locally, which meant that she ate and washed every day. Another Woman lost her Housing benefit, after her Daughter left home and she was transferred onto UC. The Man who lives in the bus stop, his Mum visits him everyday. She is in a pensioners flat, which doesn't allow guests.
Whilst there may be professional beggars (as there are everywhere), the Homeless Charity (which was started after the death of a street sleeper in 2009) says that the rough sleepers, who were from the area, are having Criminal Behaviour Orders used against them and are being targeted just for rough sleeping.
The Charity are selling Royal Memorabilia.
So it doesn't matter if anyone believes it, it has been happening.
