The President has called on all mothers to help calm the tension caused by political bickering.
In a short appeal at the end of a Mass held at San Anton Palace to commemorate Mother's Day, Marie Louise Coleiro Preca urged unity.
"As is normal in a democracy we are called to make a choice... I appeal to all mothers to help diffuse the Mediterranean temperament when we discuss politics so as not to descend into name-calling," she said.
The President urged everyone to remember that unity was important for the country.
Her appeal comes midway into a heated electoral campaign that will lead to the election on June 3.
Ms Coleiro Preca said respect, dignity and forgiveness were important values everyone should cherish.
