The Ol Kalou parliamentary by-election on July 16 is shaping up to be one of Nyandarua's most expensive contests, with leading contenders from the UDA and DCP parties heavily investing in cash handouts, gifts, and voter mobilization.

• The by-election was triggered by the death of former MP Njuguna Kiaraho.
• Key contenders include UDA's Muchina Nyaga and DCP's Kamau Ngotho.
• Intense campaign activities include daily meetings with significant financial facilitation, alongside government development project launches and distributions, such as LPG cylinders and even boats valued at Sh5 million.
