The Green and National Parties are swapping criticism at their respective annual conferences

Yesterday, Green Party co-leader Marama Davidson said the National Party was still haunted by Don Brash, accusing the party of racism.

But National Party Leader Judith Collins wasn't having a bar of that today, telling media the Greens need to 'get with the programme.'

Ms Collins says they should be more worried about her than Dr. Bash, but it's important the Greens get a bit more 'modern'.
