  We prove that a large class of expanding maps of the unit interval with a
$C^2$-regular indifferent point in 0 and full increasing branches are
global-local mixing. This class includes the standard Pomeau-Manneville maps
$T(x) = x + x^{p+1}$ mod 1 ($p \ge 1$), the Liverani-Saussol-Vaienti maps (with
index $p \ge 1$) and many generalizations thereof.
