The Turkish commercial capital must vote again for a new mayor after March's election result was overturned by the government.

Ed Butler visits the city and meets Ekrem Imamoglu, who narrowly won in March but spent just 17 days in office before the decision was made to re-run the election. Mr Imamoglu says he saw overspending and waste, and that around 10% of the city's budget could be saved.

The country is also experiencing an economic slowdown, and Ed speaks to Deniz Gider of the Turkish construction workers' union, about how it's affecting his members. Plus economist and political scientist Atilla Yesilada explains how Turkey finds itself in this current economic crisis.
