  We present results for the Standard model description of the four-lepton
production, mediated both by Higgs boson production and by other one-loop
standard model processes. The description of four-lepton final states in MCFM
v6.8 is reviewed, with special reference to the interference effects that can
occur for identical species of leptons. We present results both for
interference in the $l^+l^- l^- l^+$ and in the $l^-l^+ \nu_l \bar{\nu}_l$
final state. Prospects for further improvement in the theoretical description
of four lepton production are also reviewed.
