Nearly half of Britons think the government should raise taxes and increase spending, an annual survey of public opinion suggests.
At 48%, it is the highest proportion to support such measures since 2004, according to the British Social Attitudes survey.
The survey also found the public were becoming more sceptical of the EU.
And social liberalism was rising on issues such as same-sex relationships, pre-marital sex and abortion.
There was a more traditional attitude to national security, however, with more than half wanting strong powers on terror.
