Iran nuclear talks resume ahead of Trump's return: What's at stake?

Talks resume this Monday in Geneva between Iran and the UK, France and Germany over Tehran's nuclear programme. The discussions are a continuation of ones held last month and come ahead of the inauguration of US President-elect Donald Trump next week. The talks are described by all sides as "consultations" rather than "negotiations", but France's foreign ministry says they intend to work towards a diplomatic solution to the Iranian nuclear programme, the progress of which it calls extremely problematic.
