Narrative:

My aircraft was approaching from the southwest. We were told, 'report final for runway 10, cleared to land.' at the present time we were approximately 3 mi southwest. The tower advised our mode C was inoperative. We recycled and gave a position report and were told again 'you are cleared to land runway 10.' as we started our turn to final and began to roll out, another cessna was rolling onto final from the left base for runway 10. He was not cleared to land and at no time had a visual on my aircraft. We decided to go around and the other plane was then cleared to land from the tower. Upon landing, I contacted the tower and discussed the situation. In conclusion, the other aircraft was at fault and should not have landed. I feel the matter could have been avoided if the other aircraft verified his clearance to land before turning final. I also feel control tower could have been more alert to the situation.
