Wait... Harold Wilson and Ted Heath were better looking than Jo Grimond? Bullsh**t
Other than that, list seems about right. Although I think David Owen was more classically handsome than David Steel for 1987, but they were both pretty telegenic.
Charles Kennedy was not a bad looking man either, especially when he was younger, but as he's aged, I've noticed recently that he looks more and more like he's sucking on a sour lemon. I suppose realizing that your party is going to be decimated in the next election will do that to you.
