Lord Puttnam:

It might be helpful if one thing could be clarified. One of the real concerns in the UK, where an election campaign is just beginning, is that the micro targeting of individuals avoids the rules and regulations regarding constituency expenditure. I do not know whether that needs more explanation. National parties can spend X amount; constituencies are restricted to £15,000 each.

If those individual voters are micro targeted, it does not count as part of the £15,000. In fact what has happened is that a coach and horses has been driven through a law that has existed for 100 years that did attempt to control electoral expenditure. It sounds like a small thing but actually it is a very big thing.
