SAS sniper Danny Nightingale was jailed last year for illegally possessing a gun, he said he had forgotten about.
Although he was later freed from jail, his conviction still stands, and today Danny will appear at the Court of Appeal in an attempt to clear his name.
Speaking to Daybreak, his wife Sally said: "I'm half expecting a retrial to be honest. If I think that way then it can't be so hard when it comes."
Thanking the public for their support, she added, "we still get letters, we still get messages on Facebook, through Twitter, and the support that's been going on leading up to this appeal has been massive as well. It really pushes us forward."
