Mawbroon, I do take your point. However, it's all in the words, can it be proven that she 'wilfully' and deliberately mislead Parliament? This is the issue. Tony Blair was accused of 'wilfully' misleading Parliament over the Iraq war, and it was and has been proven since that he did, mislead us all, however, that one has been dodged for years. As has the war crimes issue.
If Esther McVey got up on the morning of her speech and deliberately and 'wilfully' thought I am going to mislead Parliament then she should resign. However, how do you prove and to be frank why would she, 'wilfully and deliberately mislead Parliament on this matter.
Varian seems to have more information that proves that Esther MCVey did 'wilfully' and deliberately mislead Parliament so once we see that info, it might make things clearer.
There are no excuses if it was 'wilfully' misleading, but proving that will be I imagine impossible.
