  • 'Soccer star Michael Owen today accepted a public apology and substantial undisclosed damages over "incredulous allegations" that his football career was over.

    Owen's solicitor, John Kelly, told Mr Justice Eady that it falsely alleged that Premier League clubs did not want to sign him and, as a result of a lack of interest, he was on the verge of retiring from professional football at the end of the season.

    Mr Kelly said: "These incredulous allegations are entirely without foundation and were obviously extremely distressing, hurtful and damaging to the claimant."'

    - PA, 3-6-9, reported here.

    Shurely Mr Kelly means incredible? I'm incredulous that such a (presumably) well-paid legal brain would confound the two adjectives so.
