Does a defendant have the right to present his own defense?

"A defendant does not have the right to present a defense of his own choosing, but merely the right to an adequate and competent defense. [Citation.] Tactical disagreements between the defendant and his attorney do not by themselves constitute an 'irreconcilable conflict.' 'When a defendant chooses to be represented by professional counsel, that counsel is "captain of the ship" and can make all but a few fundamental decisions for the defendant.'" (People v. Welch (1999) 20 Cal.4th 701, 728-729.)
