By her own admission, she is no fan of the UK Government but JK Rowling is, it would seem, a big fan of the union.
A very big fan in fact.
The kind of fan that is prepared to put her money where her mouth is.
Indeed, the kind of fan that is prepared to donate £1 million to the cause.
It is a heck of a lump sum.
Born in the West Country, Rowling has lived in Scotland for the last 21 years. She likes both countries, Which is nice.
And she thinks they are better together (as it were).
Previously she donated £10 million to set up a clinic at Edinburgh University to research treatment for multiple sclerosis.
That was an act of genuine and unquestionable kindness which will have very definite, very significant and indeed very tangible benefits.
One cannot say the same thing about a £1 million donation to a political movement.
As with large donations from private individuals to the Yes campaign, one has to wonder just what is going through the minds of those involved?
If I had a few million burning a hole in my pocket you can bet your bottom dollar (and the several million sitting on top of it) the loot would not be used to help politicians.
Many of them already have vastly inflated opinions of themselves and you really have to question what they will spend the cash on.
Will they do good or will it merely allow them to shout even more loudly at an electorate they hope to spin round to their way of thinking?
You can make your mind up, but as far as I am concerned it is a colossal waste of money.
Surely giving the money directly to a charity which actually helps the many vulnerable people politicians purport to care about would make a real difference.
Make no bones about it, giving money to a political movement is not philanthropy (not that I am necessarily suggesting Ms Rowling believes it is), rather it is madness.
She claims she made the donation because she is concerned that world class research may be put at risk by independence.
Surely it is more likely that world class research will be put at risk by a lack of funding.
There is no obligation for Ms Rowling or indeed anyone else to donate to charity. That they do so should be a source of personal pride and cause of public celebration.
However, handing over huge sums of cash to politicians of any hue is of dubious worth at best.
Of course only time will tell if Rowling’s mammoth donation casts a spell over the electorate…more likely the money will be swallowed up by the political system, dementor-style.
