When politics gets mixed up with ice-cream, the results are not always pretty.

The NSW Young Liberals have provoked a strong reaction on social media after posting a photograph in support of embattled ice-cream manufacturer Streets on its Facebook page.

The photograph posted by the NSW Young Liberals features their president, Harry Stutchbury, and Shani Murphy, who works for Liberal Party member Shayne Mallard MLC.

The pair are holding Cornettos, a brand of ice-cream made by Streets.
