Liz Truss & Trust?

There are 2 things I know about Liz Truss.

One is that she is the newly selected PPC for South West Norfolk, a safe Tory seat, and thus almost certainly the next MP for the constituency.

The second is that a few years back she had an affair with a then-High Flying Tory MP called Mark Field.

I know this because (a) I remember reading about it in the newspaper and (b) I googled all of the finalists for the seat when they were announced and I read about it (again).

If I knew about it ... why did the selectors and members of the South West Norfolk Conservatives not know about it? Does this really constitute a breach of trust? Was she, a highly bright and articulate young woman, really going into the selection to talk about her rather poor taste in men? Does this change the way they think she could do the job of PPC and MP?

I have the highest regard, and I really mean that, for the South West Norfolk Tories. I hope they manage to answer these questions.
