There’s not really room for development as in expansion.
It’s a highly populated area. My mum grew up there - 9 of them in a 3 bed council house!!! She became a teacher as this was back when people encouraged social mobility and opportunity and people took it and took personally responsibility for growth of oneself.
Im not surprised at a low turn out, I doubt many postal votes in the area. But many disenfranchised people who will believe they have little due to “illegal immigrants” rather than the truth of the situation.
I spent half my childhood in Portchester (neighbouring village) and a lot of time in Paulsgrove from birth as my nan lived there until she died and I have uncles only 12 years older than me so I know the area very well.
