St Albans Greens have selected Jack Easton as their general election candidate.
Mr Easton had previously said he would not run in the election, and had hinted at a pact with another party.
He previously stood as the Green Party candidate in the 2015 and 2010 election.
In 2015, the Green Party came last with 3.7 per cent of the vote.
This was an improvement on their 2010 performance, where they won only 1.4 per cent of the vote, coming fourth.
Two weeks ago, Mr Easton spoke of the possibility of a pact with another left-leaning party, saying: “It is something we have to address as to what is in the best interests of the country.”
However, he added he does not want to “deny our natural supporters the right to express their feelings”.
A chartered accountant, Mr Easton has lived in the constituency for nearly 20 years.
In an interview with the Herts Advertiser at the last election, he said new council homes should be built on brownfield sites, and said his party would bring the railways under public control.
So far, he only faces opposition from Daisy Cooper of the Liberal Democrats.
