The flamboyant governor of the Kenyan capital, Nairobi, has pleaded not guilty to more than 30 counts of corruption, including money laundering and receiving bribes.

Mike Sonko is accused of making more than $3m (£2.3m) through unlawful activities.

The court was surrounded by riot police after Mr Sonko';s supporters called for protests.

He is a controversial figure and has already spent time in jail.

He models himself on American rappers, wearing expensive jewellery, and golden hats and shoes.

He runs fleets of personally branded fire trucks, ambulances and hearses to assist slum dwellers.
