Alliance Party leader Naomi Long has accused Stormont opponents of being "addicted to crisis and conflict" and "simply not up to the job of actually governing".
She said the public have had enough of the "constant dramas and the political soap operas" and want politicians "focused on finding solutions".
Speaking at her party conference in Belfast, Mrs Long said electing more Alliance MLAs would "secure reform of the Assembly" and "ensure no one party can hold progress to ransom".
