Ms Ritchie said: “This letter is an attack on the community in South Down and on the integrity of our democratic process in this Westminster election.
“I have been an MP for everyone in South Down. Anyone who knows me will know that my door is open to those of all faiths, political and social backgrounds. My campaign has been based on my record of delivery for local people, ensuring that they have strong representation and real representation at home and at Westminster.
“My campaign team has reported this literature to the police and to the Electoral Commission who I trust will begin a robust investigation to find the source and hold them accountable.
“People in South Down will see through these dirty tricks. They know my character and my passion for all the people in South Down and we will not be deterred,” said Ms Ritchie.
