not a clue if it will still work but good luck with getting it sorted.If all your information is still clearly visible, ie. there could be no mistake about what is actually printed on that page, you might be OK.
Hardly worth the risk though is it.
Definitely. But give the Passport people a call before you do anything.
Very possibly. But if a new one is going to cost you £100/£150 (?) then it's worth giving them a call just to be certain.
I got a new one as I didn't want to risk it but I reckon it would've been ok. Just leave it somewhere to dry and whatever you do, DON'T try and seperate any of the pages as you'll totally ruin it, you will be able to do this when it's dried anyway.
