don't get me started on the myriad advantages of the wonderful UK identity card I bought for £30 when they came out several years ago. A fraction of the price for a passport, lighter, more waterproof, valid all over Europe, much smaller, just ideal for travelling. If those bloody Lib Dems hadn't been in government this useful item would be available to us now.
mind you, i still use it for ID on French campsites and at hotels, etc.
