Blue/Tory Boy,
I was not questioning your verbal/written word, just asking you to clarify what you precisely believe on this issue.. I can see why you are a politician, you never answer the question!
Direct is the answer then, a simple yes or no, bullet point will do...
Which of the following lakes have had 'foreign sourced' carp introduced at some time?... Most you will have heard of...
1 Harrow
2 Cons
3 Ringstead
4 Withy
5 Darenth
6 J ohnsons (Kent)
7 The Fisheries
8 Pit 4
9 Wraysbury
10 Yateley
11 Ashlea
12 Acton
13 Summerleaze
14 Wintons
15 Catch 22
If you can't answer this one then I respectfully submit, my learned friends, that this man has a problem in the morning... which end to put the toothbrush!!! 
Please then follow with a definition of an 'Engligh carp' as requested.. there's a deafening silence on this one!
Keeping it really real....
Happy carping
