A comprehensive police operation has been planned for the annual Apprentice Boys of Derry parade and pageant in Londonderry on Saturday.
Traditionally, in terms of participants, this is one of the largest parades during the marching season.
Bands and Apprentice Boys clubs from throughout the Province will take part.
Chief Superintendent Stephen Cargin, the G District commander, said the policing operation would be visible but low-key.
He said: “We have held discussions with groups representing both traditions in the city and with the business community.
“The feedback we are getting is that everyone is keen to ensure that the day passes off peacefully and successfully.
“This city has developed a tradition of peaceful parades and that has come about through dialogue and understanding in many diverse quarters.”
Ch/Supt Cargin said that the safety of everyone – whether they are participants, spectators or residents – is a key issue for police and this “has shaped” the planned policing operation.
“In particular, we will have traffic controls in place at key times during the day,” he said.
“We are asking for the patience of all road users.
“Those who wish to travel through the city centre are advised to note the traffic arrangements in place and to seek alternative routes.”
He added: “It is important that people coming to the city are mindful of their actions and how they could affect others.
“It is my hope that everyone attending the event...will show respect for others by refraining from any behaviour that may be considered offensive or which constitutes a criminal offence.”
