. Confirming a conjecture of Plummer, Thomas and Yu proved that a 4-connected planar graph contains a cycle through all but two (freely choosable) vertices. Here we prove that a planar graph G contains a cycle through X (cid:114) { x 1 ,x 2 } if X ⊆ V ( G ), X large enough, x 1 ,x 2 ∈ X , and X cannot be separated in G by removing less than 4 vertices.
