I wonder if this article is a really an unconscious railing or secret diatribe against the cost of renewing a UK passport these days :)
* Minimum cost to renew a UK passport in 1997: GBP 18 ($28).
* Minimum cost to renew a UK passport in 2011/2012: GBP 77.50 ($121).
That's 431% in 14 years or 11% per year! This does not include Post Office handling charges.
This is more than twice the highest single data point inflation (even including housing) and almost four times the annual average over that period.
Oh, and if you were tempted to fast track it for the 1-day service renewal, that's GBP 129 ($202).
