Don't really see why it's such a big deal for the Prime Minister to publish details of his Income Tax - politicians and Heads of State in other parts of the world are routinely expected to do so, in the cause of transparency/anti-corruption. Not always done with much enthusiasm or good grace and sometimes with plenty of delaying tactics.
Cameron has been promising to publish details of his tax affairs since a piece of investigative journalism by The Independent in 2012 - a follow up piece by the same journalist a few days ago was asking why the 4 year delay?
The issue of Cameron's IHT avoidance at minimum has been known for sometime and kept under the radar for as long as possible - the recent hacking of the Panamanian law firm, Panama Papers and his fathers off shore business are a co-incidental, separate but obviously related matter.
So, who is 'smearing' Cameron, exposing his private financial affairs? Not 'whingeing' , 'envious' ' lefties' or the inadequate Opposition Party.
Look at the front pages of today's Sunday papers It's the largely right-wing MSM dominated by the most fiercely anti-EU proprietors Murdoch, Dacre, Redmond et al - they are the people who most want Cameron's reputation damaged in the cause of 'Brexit'
I'd like to see more openness and transparency about politicians tax matters - didn't Boris Johnson publish his Income Tax returns during the last London Mayoral elections
There is some quite extra-ordinary stuff about Nigel Farages 'finances' online which is being quietly sidelined ATM
