Cameron is in favour of overturning the 2004 ban on fox hunting and has stated in 2010 and 2015 that a Conservative government under his leadership would give Parliament time for a free vote on the issue.

We would like to see net immigration in the tens of thousands rather than the hundreds of thousands. I don't think that's unrealistic. That's the sort of figure it was in the 1990s and I think we should see that again." In February 2011, Cameron said in response to a question in the House of Commons that too many children from immigrant families are not able to speak English when they start at school, that the parents of immigrant children had "a responsibility and an obligation" to ensure it, and that the UK must go further to ensure those settling learn English "so they can be
