Thank you for your stats, akenaton.

Whilst it's not going to be precise (your figures coming from 2005 and mine from the 2011 Census), it doesn't take a mathematical genius to note that 61,582 English born people over 65 in populatin of 5,295,403 isn't exactly 10% is it?

In case you can't do the maths, it's a little over 1%. Indeed, the entire English born population (including those too young to vote) of 408,948 amounts to less than 8%.

If you're going to quote statistics in support of your argument, at least get them remotely correct.
