To be fair she may be separated from him now and needs to keep the day job
Is she? His defence was he has the love of a good woman.
So far as keeping the day job- how much does a columnist get paid? I wouldn't place her in the celebrity league of "like em or loathe em" of say Rod Liddle, Clarkson, Richard Littlejohn and in her day Julie Burchill who earn big money.
I'd assume IK's very comfortable lifestyle is funded by private family money rather than her writing.
