I have at LEAST 20 .co.uk's that are between 100-150 days from expirary under tag names. 
You know, if I don't pay my loan, the bank warn me, then they warn me again, then they recover the money. Why do nom insist on holding these names if they are unpaid ? 
Sometimes you need to cut your losses, given the numbers you'd think they would be gone.
Some names do eventually drop tho.
