**The 't Hooft-Polyakov Monopole in the Presence of an 't Hooft
Operator**

We present explicit BPS field configurations representing one
nonabelian monopole with one minimal weight 't~Hooft operator
insertion. We explore the $SO(3)$ and $SU(2)$ gauge groups.

In the case of $SU(2)$ gauge group the minimal 't~Hooft operator can
be completely screened by the monopole. If the gauge group is $SO(3),
$ however, such screening is impossible. In the latter case we
observe a different effect of the gauge symmetry enhancement in the
vicinity of the 't~Hooft operator.
