  The Lescure-Meyniel conjecture is the analogue of Hadwiger's conjecture for
the immersion order. It states that every graph $G$ contains the complete graph
$K_{\chi(G)}$ as an immersion, and like its minor-order counterpart it is open
even for graphs with independence number 2. We show that every graph $G$ with
independence number $\alpha(G)\ge 2$ and no hole of length between $4$ and
$2\alpha(G)$ satisfies this conjecture. In particular, every $C_4$-free graph
$G$ with $\alpha(G)= 2$ satisfies the Lescure-Meyniel conjecture. We give
another generalisation of this corollary, as follows. Let $G$ and $H$ be graphs
with independence number at most 2, such that $|V(H)|\le 4$. If $G$ is
$H$-free, then $G$ satisfies the Lescure-Meyniel conjecture.
