Amid row over Europe in Tory party, Opinium/Observer poll shows 3% fall in David Cameron's approval rating
Over two-thirds of voters believe the prime minister should "listen and pay more attention" to the views of his backbenchers, amid the row within the party over Europe.
An Opinium/Observer poll found that 67% of respondents believed David Cameron should listen to what he is being told rather than enforcing his own views.
The Conservative party is in turmoil over Britain's continued membership of the EU with Cameron being bounced into offering a bill legislating for a future in-out referendum last week.
Yet just 20% said Cameron should "enforce his views and overrule them".
Meanwhile Ukip has surged to 20% in the new poll, with the Liberal Democrats on 7% and the Tories on 27%. Ed Miliband's Labour party has a 10% lead on 37%.
Ukip has enjoyed a large spike in support since the local elections with its proportion of the vote doubling since the start of the year.
Cameron has suffered a bad fortnight since the last Opinium/Observer poll, with his approval rating dropping by 3% to 29%, while those disapproving increased to 55%. Miliband's approval rating is unchanged with 24% approving of him while 43% disapprove. Liberal Democrat leader, Nick Clegg, has suffered a four percentage points increase in the number who disapprove of him, to 63% from 59%. Only 14% approve.
