Former National MP Aaron Gilmore has backed Labour stalwart Lianne Dalziel in the Christchurch mayoralty race.
Mr Gilmore revealed his preference in next weeks' local body elections in his blog.
He's vowed to vote for Dalziel in a stance which "I'm sure shocks some - not the least of which probably her!"
The 39-year-old has backed another left-leaning candidate, current city councillor Glenn Livingstone, as well as Dave East who he calls "a true Eastie and a moderate righty".
Dalziel, who last month stood down as Christchurch East MP after a 23-year parliamentary career, today welcomed the endorsement.
