We prove that every graph of minimum degree at least r and girth at least 186 contains a subdivision of K rþ1 and that for r5435 a girth of at least 15 suffices. This implies that the conjecture of Haj ! o os that every graph of chromatic number at least r contains a subdivision of K r (which is fal
