The Club legend joined pupils from Lea Valley Primary School at the Somerford Grove estate in Northumberland Park.
With the help of the children, Ledley took down a No Ball Games sign - the 150th to be removed since the campaign to get youngsters playing outdoors more was launched a year ago.
Signs have been removed following joint work between the council, Homes for Haringey and residents’ associations.
On the first anniversary of the No Ball Games signs campaign, Ledley said: “I remember seeing lots of these signs when I was growing up, when all I wanted to do was play football, so it’s great that Haringey Council have been removing them over the past year.
