Presenter Vincent Duggleby took your questions on identity protection and credit reports and put them to a panel of experts.
What steps can you take to protect your personal data?
Maybe you think someone has applied for credit in your name and want to know what to do?

If there's a mistake on your file how can it be corrected?
Or perhaps you've been turned down for credit and want to know why.
Whatever your concern, our panel of experts was here to give you advice.
