According to an article in The Guardian, O2 UK will have exclusivity with the Palm Pre in the United Kingdom, making O2 the sole distributor of the Palm Pre in the UK.
This puts O2 UK in a unique position of being able to not only offer the Palm Pre but also the new iPhone which is expected to be unveiled next month at WWDC.
O2 had apparently seen off fierce competition for the Palm Pre from rival carrier Vodafone and Orange, although O2 is currently refusing to comment on the news that they will hold exclusivity on the Palm Pre.
