My mum has just been put into tier 3. She lives alone and has health conditions which mean she is very careful. She goes out exercising but nothing else. I live 400 miles away. My mums partner lives in a village 10 miles away from her. He is still in tier 2 as it is a different district. Will she be able to form a support bubble across tiers? They meet regularly for walks at the moment (don't go in each others houses) and my mums partner brings her shopping weekly and picks up prescriptions etc. Will this have to stop? She has nobody in her tier to bubble up with or even help out.
