Meet the twins cleaning up our streets

As teenagers, these twin brothers spent time living on the streets - now they're determined to clean them up.
James and John Makanjuola have been in Southampton voluntarily cleaning street signs and bins.
It's something they've made a name for themselves doing on social media.
The pair set up their company Makagroup after going to university in Bournemouth and Portsmouth, where they realised student housing could be "grubby".
They've become so-called "guerilla cleaners" and alongside their own cleaning business, they take time to give back to the community.
'Grubby places'
John says he and his family became homeless when he and James were 15 and it was this experience that inspired them to launch the business.
John, who went to the University of Portsmouth, explained: "When I was at university, we saw a lot of dirty student accommodation.
"My flatmates were sort of dirty. I used to be the one that used to clean it up so I said 'why don't we start a cleaning company for students":[]}
