No.
This is a spectacularly bad idea.
I see the hackneyed arguments about being able to join the army at 16 and get married at 16 are being trotted out again, but that doesn't mean it is right.
I find it an absurdity that you can join the army at 16 but you can't buy a packet of fags or go into a pub and buy a pint of beer at 16.
With the exception of necessities, children under 18 are not allowed to enter into contracts.
What we should strive for is a uniform age for things like joining the army or getting married, or buying a packet of fags - and that age should be 18.
For every 16 year old who is politically aware, I reckon I could show you 20 who are not.
What happens if 16 year olds are given the vote? Will we be debating in a few years time whether 14 years should be allowed? or 12 year olds?
It is a breathtakingly stupid idea.
I note in the past it has been Labour that has suggested this. Could that be, perchance, because kids tend to be more left-leaning? I certainly was when I was in the 6th form.
