Much as I dislike Ben, both him and Yasmina, and to an extent Kate played it exactly right. Once Phillip had gone into 'protect Kate' mode and allowed his dislike of Lorraine to take over I'd have done exactly what Ben did and lay low. Yasmina clearly has problems with Lorraine, but supported her in the boardroom, Kate didn't attack Lorraine, just defended herself, and, crucially, never singled out Phillip or attempted to defend him.
Phillip bascially got himself fired last night, he may have gone anyway, but his tatics were a disaster
