One small problem, AFAIK being a member of the HoL doesn't make her a public official, because that, in itself, is not an office.
I could be wrong, but unless you prove otherwise, that's another word you don't understand.
I could of course argue with you that a member of the House of Lords is a public official, as defined by the United Nations Convention Against Corruption. I could of course point out the absurdity of having to show you a legal definition of a term that is often commonly and colloquially used outside of such a framework. Or I could quote the article in full, because I left a bit out for brevity. I have to admit I didn't foresee this quite desperate attempt. Let me quote the article in full this time.
"The solicitation or acceptance by a public official or any other person, directly or indirectly, of an undue advantage for himself or herself or for another person in order that the public official or the person abuse his or her real or supposed influence with a view to obtaining from an administration or public authority of the State Party an undue advantage'
I believe that is checkmate, Lost.
