Preheat oven to 350 degrees. Spray or grease, one 9x5x3 inch loaf pan.
Whisk together the flour, sugar, baking powder, salt & baking soda.
Cut in the butter until the mixture is crumbly. Add the beaten egg, orange zest and orange juice, mix and then add the raisins & dried cranberries, while continuing to mix.
Pour into the greased loaf pan & bake for approximately 70 minutes or until you can stick a toothpick in the loaf & it can be removed clean.
