Poll shows UK split on immigration but in favor of limiting benefits

A recent UK poll has shown that a majority of UK citizens believe that immigrants should have to pay tax in the UK before they can get social benefits in the UK or use the UK's free National Health Service.
The poll was conducted by YouGov, one of the UK's best known and largest polling organisations, for UK newspaper The Sunday Times. A sample of people were asked what proportion of immigrants they thoughtmade a positive contribution to British life; 
• 45% thought that half or more than half had made a positive contribution. 
• 46% said that they thought fewer than half had made a positive contribution. 
• 9% said that they did not know.

When asked whether they would support measures that would limit the right of people who had arrived in the UK within a certain time period, such as a year, to benefits; 
• 86% said that they would support such measures. 
• Only 7% said they would oppose them. 
• 7% said they did not know.

Similarly, when asked if they would like to see the right of recently arrived immigrants to use the National Health Service;
• 75% of those surveyed said that they would like to see the right limited
• 16% said they would not and
• 9% said they did not know.
