Class is a notion defined by certain stereotype it has a lot to do with income but there is also elements of background, attitudes and values and education too.
I don't think you can accurately categorise someone on the information that you've given because we don't know enough anout their attitudes and values from that description.
People like Alan Sugar tend to think of themselves as working class despite their money and much of that is to do with their values.
Personally I applaud their success and some of those values but I do deplore certain working class "values" such as a distrust of "book learning" and education. You often see that in people who value "common sense" over "experts".
Mind you - you see that in Upper classes too like these appalling comments from Prince Charles
