Tory ministers are considering raising the UK state pension age to 68 by the end of the next decade.
Scots born in the 1970s and after could be told as soon as the next UK Budget in March that they will be expected to work even longer before they receive the benefit.
The state pension age is already due to rise from 66 to 67 by 2028. The next increase - to 68 - was not due to happen until 2046, but an upcoming review is set to say it should be brought forward.
