@mrchocky: Then AM should have made his point clearer.
And what is so bad about that not-yet-filed tax return? Maybe they are too busy with other things right now and have arranged for a delay with the authorities? Obviously I have no idea about British tax practises, but here in Germany we have lots of exceptions to the standard rules, some of wich allow for extended deadlines.
In any case, this is none of our business. It is between MD and the tax-man.
