But if it is true, well, wouldn't that be the final kick in the teeth for the poor bloody voters of Sedgefield who have provided the vehicle for his parliamentary ambitions for the past 24 years?
Blair has always denied that he was a carpetbagger, that he alighted on the old mining seat as a convenient means of getting into Parliament and then spent as little time there as possible.
On the contrary, he has always stressed his County Durham background and his commitment to the North-East of England, although he hasn't always been able to translate that commitment into policy assistance for the region.
The least Blair now owes the people of Sedgefield who re-elected him in 2005 is to see out his term as their constituency MP.
I may be crediting the guy with far too much in the way of decency, but I just can't believe he would reward their steadfast loyalty to him by leaving them in the lurch in this way.
