My thoughts have run along a similar line, stansgran, wondering if the rate is higher where there is a higher rate of newish immigrants. My experience with the Vietnamese 'boat' woman that I spoke of earlier on this thread is one of the reasons this thought has crossed my mind, I'm sure.
pogs, I checked out the Sands charity website. That looks like a worthy endeavour. I also looked up the three MPs whose names you gave. Can't say I learned anything significant about this thread's subject matter from the Wiki articles about them. It would really help if you could do links. Are you able to highlight and copy a web page's URL (it stands for Universal Resource Locator but you don't need to know that; I didn't till I asked DH just now!)? It is the internet 'address', if you like, of the page you're on. Try going to the top of your page now and click on the bit where it says gransnet.com. It should expand to show the whole address of the page. That's the first step.
