Melanie Phillips, an apology?

I knew nothing of this until Debbie Fink posted on it to the Just Peace UK list but here's The Independent Diary:

Lovers of the unusual, rejoice! Within days Melanie Phillips will make a public apology. In July 2008, Mad Mel lifted and embellished a mistake from the neocon website, Harry's Place, regarding Mohammad Sawalha, a Palestinian-born British man whom Al Jazeera had mis-transcribed referring to "evil/ noxious" Jews at a rally. In fact, as Arabic experts later confirmed to High Court superstar Tugendhat, he referred to the "Jewish lobby". Al Jazeera corrected it instantly, and Harry's Place later, yet MM magisterially ignored requests for a simple correction until a trial was imminent, when she caved. This unwonted arrogance has presented a six-figure bill for damages and costs to The Spectator, which at the time of writing continues to host her deliciously deranged blog.

Deliciously deranged? What can they mean?
