I live in a large block of flats and I'm a bit annoyed to see a group with our local MP walking up and down the corridor. It's difficult to keep strangers out of this building because there are so many people constantly coming in and out. Tenants, visitors, couriers, contractors etc. So anyone can come in behind them.
Also our polling station is at a nearby block of flats that has a community room. Does this mean they're not allowed to go canvassing at the flats in that block?
