Whether it's appropriate language for a (p*ssed) deputy leader to make (*),
@NeilR is broadly correct. The fact is that it has already provided the hostile press with another stick to hit Labour with and to link it to this 'sort of thing', even though it's now seems to be more unlikely as facts emerge) is a golden opportunity to further stick the boot in. That link is already easier to make because the language in the media coming from politicians of all colours and the the political commentariat this weekend is about "
coarsening of political discourse" and "
social media death threats" so its all too easy to join the dots.
(*) Being drunk at a party conference is their call but to do so and not think that someone is there to record it is at best a lapse of judgement for someone who is followed by media. That said, it's not just Labour politicians that should be more careful with their words / behavior in public. Therese Coffey and some of the other yahoos at the Conservative conference spring to mind.
