I am intrigued, Iains. My wife left work at 60 but does not draw any pension or have any other source of income until she is 67. Do you insist she should not have the vote?

I think your wife should re-check this.
Taking your comment at face value, and giving her the youngest possibility (60th birthday yesterday) her state pension would be due at age 66. If she's any older than 60 years and one day it may be even earlier.
