Children in the borough were praised for completing a summer reading challenge during a ceremony.
The deputy mayor of Merton, Councillor John Bowcott, congratulated 2,922 children who were involved in the competition in Raynes Park Library last week.
A total of 1,446 youngsters completed the Story-Lab themed challenge for their record-breaking participation this year.
He also presented certificates to the children as well as prizes.
The Travelling Interactive Theatre for Children (TITH) gave a performance during the event.
Coun Bowcott said: "It is great to see so many children reading and taking part in this great competition. Reading is an excellent hobby for everyone, especially children, and their dedication to this worthwhile challenge deserves to be recognised."
Anne Sarrag, of the Reading Agency, said: "Reading is such an important skill and we are passionate about getting as many children reading as possible.
"Merton has worked particularly well on the campaign, which is why we are here. The council is a great ambassador for the Summer Reading Challenge."
The national Summer Reading Challenge encourages children to read six library books over the summer holidays with incentives, activities and events designed to create a buzz around reading.
