I want to get domains from a uk company gone bust - how?

[wxdqz]

I'm interested in a couple of .co.uk domains which are registered to a UK limited company which has gone into liquidation (gone bust).

The registrations expire March 2008.

I have contacted the liquidators, but they say that the domains were leased and therefore do not form part of the companies assets and can't help.

Any ideas?

Will I just have to wait for them to expire and try to snipe them? - how do I do that?

Thanks in advance for your advice.
