Oh yeah, this is coming.

From Mark Steyn's latest column:

According to Nicholas Hellen in this weekend's Sunday Times, "The Inland Revenue is considering recognising polygamy for some religious groups for tax purposes. Officials have agreed to examine `family friendly' representations from Muslims who take up to four wives under sharia, the laws derived from the Koran. Existing rules allow only one wife for inheritance tax purposes. The Revenue has been asked to relax this so that a husband's estate can be divided tax-free between several wives."

...you see how easy it is to start talking about polygamy in a nuts-and-bolts, incremental, legal-harmonisation, partners'-benefits, insurance-agent kind of a way. Just tidying up a bit of the fine print, old boy. Nothing to worry about. But, once a polygamous union is recognised as such by the Inland Revenue for the purposes of avoiding 40 per cent death duties, how long can the broader British state withhold recognition? No lack of taxation without representation!
