Spectral problems for the Dirac operator with regular but not strongly regular boundary conditions and complex‐valued potential summable over a finite interval are considered. The purpose of this paper is to find conditions under which the root function system forms a usual Riesz basis rather than a Riesz basis with parentheses.
