Judith Collins says she has no regrets about spending the last 24 years in Parliament. 

The senior National MP has delivered her valedictory speech as she prepares to move on, to head the Law Commission. 

Collins has held numerous ministerial portfolios in her time in politics and led National to the 2020 election. 

She told Mike Hosking she's grateful for everything she's been able to do. 

Collins says it's been an interesting career, and she never held a portfolio she got bored with.
