Tom Logan, chair of the eight-strong gala committee, has confirmed that he plans to step down at the group's annual general meeting next month.
Mr Logan, who has frequently lamented a lack of support for the gala
committee in recent years from the wider community, told the Courier that his resignation was due to a number of factors, including "other work commitments".
He explained: "I have been saying for the last couple of years that I would step down but when no one came forward to replace me I always ended up sticking around to make sure that the gala went ahead.
"I feel now that I have done everything I can where the gala is concerned to bring it forward and expand it as much as possible. I think that it is time now for someone else to step in and see if they can do a better job."
The children's gala day, which is the main event of the week-long programme, regularly attracts more than 1,000 people of all ages to the Ross High School playing fields. The schedule also includes a variety of activities, including a teddy bears picnic, pet and talent showS, and a fancy dress parade.
Mr Logan has previously hit out at critics of the gala committee, claiming that those who were quick to complain about the organisation of events made no effort to contribute their own time to improve the celebrations.
A number of residents, including members of Tranent and Elphinstone Community Council (TECC), were unhappy when the committee chose to hold the gala day on a Sunday once again this year, despite a 2010 survey showing that the majority of participants would have preferred the event be held on a Saturday.
The efforts of the committee have not gone completely unnoticed however, as the group was honoured with an award for 'best community group' at TECC's Achievement Awards, in June.
It's understood that between two and three other committee members are also planning to leave the group, leaving just a handful of volunteers to organise next year's gala.
Mr Logan urged residents who do not wish to the see the celebrations cease permanently to attend the AGM and volunteer their efforts.
All are welcome to attend the meeting, taking place on October 10 in Tranent Day Centre at 7pm.
