I read with interest the article about Ms Teri Knight (The Argus, March 23) who was questioned over the validity of her disability badge.

Two years ago I had a knee joint replacement. Nine months prior to the operation, I was virtually crippled. I could not walk more than 30 yards without considerable pain and discomfort.

In spite of this, I was unable to obtain a disability badge.

However, since the operation I cope perfectly well.

So do we assume the operation that Ms Knight had was a complete failure or is her parking badge automatically renewed regardless of her condition.
