Sorta suprised its only 6.

Given its clearly a polutical hot potato. Thanks to tories intentionaly using it to divide and anger some voters.

I cant help but wonder about motives.

The most non negative reason i can think of for MPs not to be bothered. Is fear that thos is more common amonst younger folks who grew up with the idea more acceptable.

As those folks are also more likely to be living at home with family. There is a reasonbly high chance the data would be inaccurate depending on views of head of household.

IE any subject that is politically sensitive would need indevidual secret collection of data. As not everyone would be comfortable discussing it with family members.
