There is a website devoted to the idea of 'Renewing your passport as a protest' against ID cards.
This is an idea I considered a little while ago
(and am currently promoting every time an ID card post hits the homepage). The problem isn't when the cards start to be issued (projected for 2010), but instead is the database behind the card, which starts much earlier.
"... anyone who feels strongly enough about the linkage not to want to be issued with an ID card in the initial phase will be free to surrender their existing passport and apply for a new passport before the designation order takes effect."
â€” Charles Clarke, on 21st March 2006.
For myself, assuming that we don't decide to make a booking in the next couple of weeks, my renewal will be going in on about the 30th May.
I would encourage everyone who opposes the ID cards to take part in this campaign.
