Abstract
Parabolic subgroups are described for the full and special linear groups over a commutative ring R which contain a principal congruence level a, where a is an ideal of R such that R/a is semilocal. It is assumed that R is generated additively by its invertible elements and that the ring identity can be expressed as a sum of two invertible elements.
