If any??
There are SO many issues with Johnson - he is involved in at least 3 different potential scandals at the moment - the supressed Russia Dossier, the Jennifer Arcuri misconduct allegations and Vote Leave electoral fraud. His personal is marred with allegations of sleazy conduct and dishonesty. His working life outside parliament is a similar story of lies, conniving, incompetence.
Yet I don't see endless threads lambasting him - it just seems to be shrugged off with a 'well we all know what he's like'. Why is he getting such an easy ride on all this?
