How Brexit will affect the balance of power in the European Parliament

Given the UK has one of the largest contingents of MEPs, how will Brexit change the way political parties are aligned in the European Parliament? Angelos Chryssogelos writes that the effects of removing British MEPs from the Parliament will be wide-ranging, with sovereigntist forces potentially strengthened inside the centre-right EPP, the centre-left S&D becoming more oriented toward an anti-austerity platform, and Eurosceptic forces more likely to consolidate around the ENF group led by Marine Le Pen.
