Apologize for what? speaking the truth?
Sturgeon has a lot of other things to possibly apologise for right now.
I was never much of a fan of the SNP, but I never thought of Sturgeon as corrupt - unlike Salmond she actually seemed to me to be pretty competent and effective as a leader. Though at the moment the situation seems as clear as mud - I don't understand what's going on with the SNP.
But I don't think it's possible to overstate how morally-repugnant Braverman is, or how inept and useless most of the rest of what remains of the Conservative Party are.
