A poll carried out for the BBC's new The Big Questions show has found that four in five people believe Britain to be in moral decline.

According to the survey of 1,000 people, only nine per cent disagreed that moral standards were falling, reports the BBC.

Religion still kept its place of importance, with 62 per cent agreeing that religion was an important moral guide for the nation.

Only 29 per cent disagreed that faith was important in shaping a nation's morals.

The survey also tapped into people's beliefs about anti-social behaviour. It found that people were less likely to intervene if they saw someone behaving antisocially than if they saw a stranger who had collapsed.

While 93 per cent of people said they would help a person who had collapsed in the street, only 61 per cent said they would try to break up two children fighting, and only 32 per cent said they would intervene if they saw teenagers spraying graffiti.

The survey was carried out by polling company ComRes on behalf of the BBC between 31 August and 2 September.

It also found a generation difference in attitudes to religion. People between the ages of 16 and 24 were more likely than those in older age categories to agree that religion had a key role to play in guiding the nation's morals, the survey found.

The Big Questions will broadcast on BBC One on Sunday 9 September at 1000 BST.
