Sky News contributor Graham Richardson says John Howard is "one of the two" great post-World War Two prime ministers and is a person in which he has enormous respect for.
Mr Richardson said John Howard "was a tremendous prime minister".
"And the introduction of the GST, which was an incredibly courageous political move, was a great move for Australia".
"So, I have enormous respect for John Howard".
"I admired Howard, it's pretty well that simple".
