Question Time host David Dimbleby will turn on the festive lights in Polegate at the beginning of December.
The big switch on, which will take place outside the council offices, will form part of a large annual Christmas event in the town on December 1.
There will be a wide range of activities and attractions on offer throughout the afternoon and evening. The event will have a Dickensian theme and will include stalls, dancers, singers, bands and a fancy dress parade.
Organisers are promising a fun event for all the family with a visit from Father Christmas and miniature train rides to keep the little ones amused.
Local shops and cafes will also be entering in to the Christmas spirit by dressing their windows and offering traditional fare such as mince pies and roasted chestnuts. Some businesses will also be offering presents and activities to visitors.
Residents and visitors are also being encouraged to dress up in Dickensian and Victorian dress for the event.
Jayne Bigsby, one of the organisers of the event, said, “Following on from last years success it is likely to be a very busy event.
“Fortunately Polegate is well served by buses and trains and there is a car park but it is limited to a few hours and we are sure you will want to stay a lot longer.
“Even Father Christmas is arriving by train from the North Pole, so come and greet him as he arrives in Polegate and then visit him at his grotto.
“There is a present for every boy and girl who visits him.”
There is no charge to attend Polegate’s Christmas event but much of the proceeds will benefit local charities.
The day will start with a town crier announcing the opening at 1pm and will end at 5pm at St John’s Church Hall for mulled wine and mince pies.
