Editorial: Dirt remains 'undished' as Sorrell settles

So Sir Martin Sorrell has agreed to accept £150,000 (which amounts to no more than petty cash for the WPP boss) to settle the libel action against two of his ex-senior managers. It was a racy case while it lasted, with some spicy allegations being aired. What a pity we never got to watch the final act. It was so hugely enjoyable.
