Well I wouldn't compare Alan Hansen with Morecambe and Wise and of course the Director General is not doing so. Simply making the point that the BBC pays its top personalities a lot of money.
Comparing audience figures, by the way, is rather dubious. Morecame and Wise had their heyday at a time when there were only 2 or 3 TV channels. Nowadays there is a lot more choice.
It's a typical, highly emotive and subjective piece of Daily Mail tosh. It starts with a populist headline to "get them going", works itself up into a lather, does its usual "critics also pointed out ..." bit (which critics in particular I wonder?) and only really seriously addresses the issue right at the bottom where you get the sane response from the BBC that there is not, in fact, a direct comparison being made between Hansen and M&W at all.
