Solar eruptive events, such as coronal mass ejections, supply mass and magnetic field to the heliosphere, drive space weather events at the earth and play an important role in the evolution of the global solar magnetic field. Understanding the physical processes which trigger and drive these events is one of the key questions in solar science. This talk will look at how the fragmented field in decaying active regions is organised into a partly coherent structure of a flux rope before its eruption into a coronal mass ejection. It will look at what can be learnt from combining observations of CME source regions with non-linear force-free field reconstructions of the coronal magnetic field.
