In a stuffy matatu ride in Nairobi one hot January morning, Mueni can't believe the headline she reads over the shoulder of another passenger - 'Kenya Power seeks increase of electricity prices by up to 78pc'.
It's barely a month since electricity prices already went up by 15 per cent!

She was already struggling to keep up with rent, her daughter's school fees, and the sharp increase in the cost of food.
