The Liberal Party has suspended a campaign director in the 2015 NSW election, after he was charged with electoral crimes in a marginal seat where the Australian Labor Party candidate was anonymously smeared as a paedophile.

The NSW Electoral Commission has taken action under the Parliamentary Electorates and Elections Act against Jim Daniel, who ran the campaign for the seat of East Hills, which MP Glenn Brookes unexpectedly retained by just 628 votes, or 0.8 per cent, in 2015.

During the campaign about 300 posters of ALP candidate Cameron Murphy, a human rights lawyer who has an Order of Australia and is the son of High Court judge Lionel Murphy, were defaced with stickers saying "paedophile lover," "stranger danger" and "our children are not safe".

In 2015 ALP MP Lynda Voltz, under parliamentary privilege, accused Mr Daniel, who is on Bankstown City Council, of organising the defacement of the posters.
