I consider the effects of including a variety of new LHC data sets into the MMHT approach for
PDF determination. I consider the impact of fitting new LHC and Tevatron data, which leads to
clear improvements in some PDF uncertainties. There are specific issues with ATLAS 7 TeV jet
data and I include a discussion of the treatment of correlated uncertainties and briefly the effects
of NNLO corrections. I also present preliminary results with the inclusion of the high precison
final ATLAS 7 TeV W,Z rapidity-dependent data.
