Senior Labour MP Kelvin Davis calls time on political career

The senior Labour MP, and former deputy leader Kelvin Davis is calling time on politics ahead of a term in opposition. Mr Davis, who was first elected in 2008, will quit Parliament effective from Waitangi Day. He was defeated by Te Pati Maori in Te Tai Tokerau in October, but stayed on as a list MP. He says he doesn't want to become a bitter and frustrated person while in opposition.
