Measurements of deep inelastic ep scattering at high Q**2 
performed at HERA between 1994 and early 2000 by the H1 and ZEUS collaborations
are presented. The data are compared to expectations from the Standard Model 
and are used to set constraints on various extension models.
In the second part, the previously reported observation of events with an 
isolated high Pt lepton and missing transverse momentum is discussed, 
the observed rates and event characteristics being compared 
to the expectations from Standard Model W production.
