Let
$(X,B)$ be a projective log canonical pair such that 
$B$ is a 
$\mathbb{Q}$-divisor, and that there is a surjective morphism 
$f: X\to Z$ onto a normal variety 
$Z$ satisfying 
$K_X+B\sim _{\mathbb{Q}} f^*M$ for some big 
$\mathbb{Q}$-divisor 
$M$, and the augmented base locus 
${\mathbf{B}}_+(M)$ does not contain the image of any log canonical centre of 
$(X,B)$. We will show that 
$(X,B)$ has a good log minimal model. An interesting special case is when 
$f$ is the identity morphism.
