Detagged domain name

Several years ago i signed up for a Dial-up ISP which offered a free co.uk domain name and hosting. I used it for a while and it was fine. For various reasons the the site was taken down by the ISP and I couldn't log into the FTP and all that was left of the site was a error page.
It sayed like that for few years and I've always wanted to own the domain name officially. I originally used a fake name to register.
Anyway now i whoised the name and it's been DETAGGED although the Registrant is still my by old fake name.
Basically how long will i have to wait for it to become available for me to register it officially?

here's some stuff from WHOIS
