Foreign Secretary loses her memory?

The Foreign Secretary Margaret Beckett in response to her apparent setting up by Rory Bremnar has claimed she does not remember such a conversation taking place.

Yet she then says "If he has done as he suggests, it is both an unprincipled and unpleasant breach of privacy." Well the one person besides Rory Bremnar who would know if such a conversation took place is Margaret Beckett herself.

Surely the conversation took place or it didn’t. It can’t be both.
