I recall Edwina Currie getting the same-sex age of consent lowered from 21 to 18, back in the day, the same woman who told pensioners to wear knitted hats indoors if they couldn't afford the heating bills...and many other disasters.
In her case though, it was a very obvious possibility that as a very human human being, who had had an affair with (!!!) John Major, and had had local government experience as well, she understood that people have sex even when someone says they shouldn't, and the current law was just making things worse for everyone.
Liz Truss - is this another self-involved and cynical political move, or is she raising this due to sincerely held personal views?
