LONDON -- Leading Japanese industrialists with big investments in Britain -- especially in the automobile industry -- have launched a chorus of complaints in recent weeks.

Their concern is that the pound is both too high and too volatile against the euro and that this makes their operations uncompetitive. They may, they say, have to switch future investments elsewhere. They want the British to join the euro currency system soon, preferably at a nice low rate, and scrap the pound for good.

Is it wise for these important investors to involve themselves in what is in British domestic terms, a super-sensitive and major political issue?
