I think the Hinduja Brother money went through her company (thus exonerating Vaz of receiving it himself) as a fee for "immigration law advice". I wonder if she has given the DM an exclusive in return for them not digging deeper on other matters and/or it's a ploy by his PR - his wife forgives him, she is worried he could commit suicide - so that the public consensus is he and his family have suffered enough so there is no need for him to resign as an MP or be further investigated.
He should have had to stand down in 1989 over his behaviour regarding the fatwa against Salman Rushdie.
