Question 75
The incircle of triangle $ABC$ touches the sides $AB$ and $AC$ at points $K$ and $L$, respectively. The line $BL$ intersects the incircle of triangle $ABC$ at point $M$ ($M \neq L$). A circle passing through point $M$ touches the lines $AB$ and $BC$ at points $P$ and $Q$, respectively, and intersects the incircle of triangle $ABC$ at point $N$ ($N \neq M$). Prove that if $KM \parallel AC$ then points $P$, $N$ and $L$ are collinear.
