Former Green MP speaks at National Party 'BlueGreen' event

A former Green MP who quit the party last year has made a brief return to the world of politics - this time, at a National Party event.

Kennedy Graham spoke to a group of high ranking National MPs at the party's annual 'BlueGreen' environmental retreat.

The former diplomat, who has repeatedly criticized National's policies in the past, called for inclusion to tackle climate change.

"There is nothing more critical by way of an ingredient to success in this, than in genuine cross-party dialogue," he said.

Mr Graham resigned from the Green Party list in the lead up to the 2017 election following co-leader Metiria Turei's admission of benefit fraud.
