A recurring question in reputation management is when to use a right to reply and when it's best to keep shtum.

There are times when it's right to add your voice to an argument; raising issues, marking yourself as an panacea to others or exercising a right to reply can all be reasons to comment.

The risk of entering a melee, however, is that instead of separating yourself from the crowd you become part of it.

 Jeremy Corbyn's late announced attendance of the election debate was a strategic move serving the narrative of an arrogant Prime Minister who simply didn't consider it necessary to try and win votes. Roundly criticised for not attending by the attendant political leaders, press and viewers alike, the programme's format exposed one of May's key vulnerabilities.  

However, the views on whether his attendance actually delivered any increase to Corbyn's support are very mixed.

Juliet Samuel of The Telegraph said of his performance: "His appearance alongside the leaders of minnow parties was meant to underline Theresa May’s absence. Instead, he looked like he belonged there." While her colleague, Asa Bennet declared: "The end result was that Mr Corbyn was brought down to their level. Never wrestle with a pig, George Bernard Shaw once warned, you get dirty and the pig likes it."

Certainly these debates have left Prime Minister Theresa May exposed, however, Corbyn's own presence may have lowered, rather than raised, his reputation for some observers.
