Leaving immigration aside. If you could implement a (new) law in the UK what would it be.

I'm surprised that none of the female posters on this site haven't suggested that leaving the toilet seat up be made a hanging offence!

Without hesitation I would implement a law that prevented private companies from accessing everyones' personal information for a fee. Definitely.

Easy to say, but there would then need to be a LOT more prisons.. either that or have prisons in 'cells at home'.

I would make it compulsory for women not to moan! ;O)

Tissy //I would ban all wood burners, my house always stinks of my neighbours smoke.//

I thought there was already a law for that.

First 5 would do 'cos i'm not a greedy person🤑
