Welsh Liberal Democrats leader Kirsty Williams says the resignation of Wales' education minister shows his position became untenable.
She was speaking after Leighton Andrews announced his departure following a row over his defence of a school which faced closure under his own surplus places policy.
Mr Andrews had been seen holding a banner in support of Pentre Primary School in his Rhondda constituency.
