Jonathan Ross is bringing star quality to Jewish Blind & Disabled's PETrons campaign, to which supporters sign up their pets and make a £5 monthly donation.

The broadcaster has agreed to judge a photo competition of PETron images. A goodie bag will go to the pet featured in the winning picture.

"Jonathan is a good friend of Jewish Blind & Disabled [he hosted a lunch which raised £70,000] and we're excited to see which picture gives him the biggest smile," said Hazel Kaye, JBD's chief executive.

"The PETron campaign has been an incredible success, helping raise both money and awareness of our work."
