The Bishop-Phelps-Bollobás property for numerical radius in l(1)(C)

We show that the set of bounded linear operators from X to X admits a Bishop Phelps Bollobas type theorem for numerical radius whenever X is l(1)(C) or c(0)(C). As an essential tool we provide two constructive versions of the classical Bishop-Phelps-Bollobas theorem for l(1)(C).
