Brian Wilson was the party's first MLA in Northern Ireland
The Green Party in Northern Ireland was first elected to the NI assembly in 2007.
Brian Wilson was elected in North Down and it represented a significant breakthrough for the party.
Breaking the foothold that traditional orange and green parties hold in Northern Ireland has been a challenge for non-aligned groups for many years.
The party failed to get elected to the multi-party talks in 1996, negotiations which led to the Good Friday Agreement. In the Northern Ireland-wide poll, the Greens took just 3,647 votes.
But the peace process appears to have brought new opportunities.
The party has been steadily improving and in the 2009 European Election took more than 3% of the vote with Steven Agnew as a candidate, polling 15,764 votes.
This was more than three times the Green's previous poll result.
The party intends to field three candidates in the General Election. The party supports a reduction in Carbon Emissions to address the effects of climate change.
It is the only Northern Ireland party that does not accept corporate donations. The party is backing residents opposed to the expansion of Belfast City Airport.
The Green Party works in cooperation with other Greens across the European Union, and has a close relationship with its counterpart in the Republic of Ireland.
The party has three councillors.
