I wish i could just tippex the dual entries out now, but i don't think that would go down too well with the CAA.
The thing is that as one of you said, these flights that i did were operated as me being the PIC as i was the one building the hours towards my IR but with my lack of experience and know how of the rules and regs i stupidly(in hindsight) let my mate who was an instructor come along for the ride and allowed him log the time aswell.
Thankyou potkettleback for your advice on what to put in my grovelling letter to write to the CAA, which i'm going to start writing this afternoon.
Cheers for the support and advice
