Add WMTS layering for leaflet. I modified a bit the code from IGN that you can find here:
http://api.ign.fr/tech-docs-js/examples/js/geoportalLeaflet.js
In order to use this plugin, include the leaflet-tilelayer-wmts.js on your page and use it as follow:

var layerIGNScanStd = "GEOGRAPHICALGRIDSYSTEMS.MAPS.SCAN-EXPRESS.STANDARD";

var url = "http://wxs.ign.fr/" + ignKey + "/geoportail/wmts";
var ign = new L.TileLayer.WMTS( url ,

}
);
var map = L.map('map').setView([48.505, 3.09], 13);
L.control.scale({'position':'bottomleft','metric':true,'imperial':false}).addTo(map);
map.addLayer(ign);
var baseLayers = {"Carte IGN" : ign};
L.control.layers(baseLayers, {}).addTo(map); </script>
