The surprise resignation of Japan's Prime Miniser Shinzo Abe sent shockwaves through the country's political establishment. The 65-year-old quit citing health reasons related to ulcerative colitis, a chronic bowel disease he's lived with since he was a teenager. Abe apologised to the Japanese people and said he did not want his illness to get in the way of decision-making. Described as a nationalist, he's struggled to introduce aggressive economic reforms. So how far has he succeeded? And how will Japanese remember him? Presenter: Adrian Finighan Guests Tomohiko Taniguchi, Special Adviser to the Cabinet of Shinzo Abe and professor at Keio University.
