John Rentoul has shown his unfitness to be a journalist, let alone political commentator, by his crass tweet as the tragic events in Paris unfolded. Rentoul chose to use this calamity to attack Labour Leader Jeremy Corbyn. The tweet was deleted, but it's out there now. This is an abuse of a responsible position and a gross lapse of judgement from somebody who has demonstrated an appallingly inadequate sense of proportion and priorities. John Rentoul must go.
