It is easy to be critical of summits and the communiques that come out of them. There is always lots of politics involved, as different agendas meet and different expectations clash. Perhaps the 2016 Anti-Corruption Summit really will be the start of something new. But given what the leaders have been able to agree on, it might make sense to keep the bunting on hold for just a little while longer.
David Cameron will today be smarting from the faux pas of making an acutely embarrassing indiscretion under the glance of cameras. Just days before the 2016 anti-corruption summit, the UK Prime Minister will be hosting, he was caught on camera in discussion with the Queen and the Archbishop of Canterbury, describing two of the countries sending delegates to London as "fantastically corrupt countries".
Fifa, football's world governing body, will once again be meeting in Zurich this week. Following eight months of drama, intrigue and, at times, outright absurdity, the organisation is hoping both to elect a new president and agree a new package of reforms. Indeed, it's hoping to draw a line under the most tumultuous period in its 112 year history.
Tyrannical and thoroughly disagreeable though he is, Mr Putin stands for nationalistic pride, a crucial buffer against the perils of American foreign policy and a determination to defend a revived Russia on the world stage, and her citizens abroad. Three things I respect, and three things a shrinking world desperately needs.
The truth is that in tennis, and most other major sports, only a small amount of resource is invested in fighting corruption. They are simply no match for the organised crime gangs, international gambling syndicates, and greedy dishonest officials. Sports governance has become a wild west, but we need more than a lone ranger to combat it.
Governments, international organisations, civil society and businesses have worked hard over the past twenty year to stop corruption, but it is still a huge problem. We must press on together and build on the growing momentum - through concerted, international efforts and strong political leadership - to expose and confront corruption wherever it occurs.
Players are easy targets. We've got a lot of money to throw around and half of us don't know what to do with it; so a lack of business acumen, twinned with poor or dishonest advice, quickly becomes a recipe for disaster. The situation isn't made any better of that the macho attitude has disdained asking for help or admitting you have a problem.
Way beyond the violence and corruption from City of God, Brazil finds itself in a very dangerous situation and dark times might be ahead. And I'm not even talking about economy. When I left my home country about six years ago, things seemed to be progressing for a better situation, with a decrease in poverty and hunger and a growing economy. There was a lot to be done and I was aware that it would take a long time, but then things changed.
When parents and those in-charge of small children are asked what it is that they have done all day, the answer can be hard to quantify. The exact details may be hazy, some of it may sound like nothing much at all and there are probably moments they've forgotten to account for, but it covers a great deal.
