Let's get this correct :-
€2M * 0.78 (exchange rate from earlier) / 52 (number of weeks in year) = £30,000 p/w net of tax etc.
So, if we're generous and say he's paid 40% tax (yeah right) and NI is capped at an upper limit so can (mostly) be ignored.
Then we divide by 60 and multiply by 100 (the net is 60% of the gross) to get gross amount, in this case £50,000 p/w.
So, this has a lot of assumption and I doubt whether they would actually pay that much tax etc so £50k p/w is about right!
