  We discuss the necessary steps for implementing an angularly ordered (AO)
electroweak (EW) parton shower in Herwig 7 multi-purpose event generator. This
includes calculating the helicity-dependent quasi-collinear EW branching
functions that correspond to the full range of final-state EW parton shower, in
addition to the initial-state EW gauge vector boson radiations. The results are
successfully embedded in the AO Herwig 7 shower algorithm and have undergone a
set of comprehensive and conclusive performance tests. Furthermore, we have
used this EW parton shower algorithm, alongside the existing $QCD+QED$ AO
shower, to predict the angular distributions of $W^{\pm}$ bosons in LHC events
with high transverse momentum jets. These results are compared against the
explicitly generated underlying events as well as the existing ATLAS data to
show the effectiveness of the newly implemented $QCD+QED+EW$ AO parton shower
scheme.
