LONDON - Seven out of 10 Britons are concerned action in Libya could result in forces being sucked into a long Iraq-style conflict, a poll showed on Tuesday, while nearly half said the government should not have intervened militarily. The ComRes poll carried out for the Independent newspaper found 47 percent think the government was wrong to launch air strikes against Muammar Gaddafi, against 43 percent who approve of the decision. A ComRes/ITN poll undertaken only a week ago found that 43 of the public disagreed with the action, suggesting opposition was hardening. Tuesday's poll found that 71 per cent of those questioned feared the intervention could drag on, despite Prime Minister David Cameron insisting that Libya is "not another Iraq". Respondents' views were split along party political lines. A majority (58 per cent) of Conservative voters, the leading voice in the coalition government, backed the intervention. That compared to 45 per cent of Liberal Democrat supporters �" the junior coalition partner �" favouring action, and 46 per cent of supporters of the opposition Labour Party agreeing. ComRes interviewed a random sample of 1,000 adults by telephone between March 25 and March 27.
