Abstract
In this paper we describe a new model of multiple partonic interactions that has been implemented in Herwig++. Tuning its two free parameters we find a good description of CDF underlying event data. We show extrapolations to the LHC.
Comments: 25 pages, 16 figures, plots and tune updated for Herwig++ 2.2.1, additional paragraph on the LHC extrapolation
