Jim Chalmers has joined Chris Bowen in declaring he won't be running for the Labor leadership.
In a statement on Thursday morning, Chalmers said he had given running "very careful consideration" and there were good reasons to put his hand up.
"But in the end I couldn’t be assured of winning, and if I did win the extra responsibilities of leadership would make it much harder to do my bit at home while the youngest of our three little kids is only five months old," he said.
The shadow finance spokesman thanked colleagues, members, activists and people around the country who had contacted him "and urged me to run on a platform of generational change".
