I believe the domain drops then some 6 to 8 weeks after it is suspended?
You would then be able to register it if you got there first (ahead of the mass volume of comapnies around that are doing it already) - I believe you just need to keep checking every day
I'm new on the forum and hopefully my comments are correct please correct me if not (also for my own knowledge)

It's happened to one of my sites a coupl'a days ago. I think it's due to Nominet's new "positive renewal" scheme which started Nov 03.
I think in my case, the registrar has goofed and not complied with Nominet's scheme quickly enough - Your/my post I fear may be just the start.
Nominet are currently deleting tens of thousands of detagged domain names every month but the competition for the premium ones is fierce. If the name that you are after is particularly good, checking the whois just once a day is likely to lead to disappointment.
... so your best bet is to recruit help by signing up for the domain yourself with one of the drop-catching companies - if the slot's still open, that is.
