UUP boss Mike Nesbitt has condemned those who have placed election posters on a County Down bonfire.
The election posters of Alliance's Anna Lo and Sinn Fein's Martina Anderson were both placed on a bonfire in Bangor recently.
Anna Lo's posters were also placed on a bonfire in Carrickfergus.
Mike Nesbitt said: "It is perfectly possible to celebrate one's cultural identity without having to resort to burning election posters or seeking to offend anyone else.
"I have previously called for actions to be lawful and peaceful, but it is equally important to stress that they must also be respectful."
A spokesperson for the Alliance party said: "This is a hate-filled crime which is an example of gross intolerance.
"It is hypocritical for the organisers of these bonfires to call for respect for their culture when they are burning posters of politicians."
