Close encounter of the four legged kind

I was walking between Portcullis House towards Westminster Hall when I saw a dog on a lead. I though my god - thats a funny looking guide dog (assuming it would be leading one former Home Secretary).

But no, my eyes deceived me. It was Tory Vice Chairman and well known dog lover Andrew Rosindell. I seem to remember he had a dog called Buster (but I believe he passed away). I wonder who his trusty companion is supporting in the leadership campaign. Unfortuantely mans best friend was giving nothing away.
