Abstract: A compact metric space $ S$ is constructed and it is shown that there is a bounded linear operator $ T:{L^1}[0,1] \to C(S)$ which cannot be approximated by a norm attaining operator. Also it is established that there does not exist a retract of $ {L^\infty }[0,1]$ onto its unit ball which is simultaneously weak* continuous and norm uniformly continuous.
