The British prime minister David Cameron has announced new measures to make it harder for people to hide the proceeds of corruption in offshore accounts. Most British overseas territories that had tax havens will now share information with the UK authorities. The prime minister has been under pressure since it emerged that he used to hold shares in an offshore trust. Rob Watson reports. After days of damaging headlines and much insinuation and speculation on social media, David Cameron mounted a typically robust defense of his personal tax affairs and the record of his government. He has done nothing wrong and his government would be improving both the transparency and scrutiny of financial masses in the UK's oversea territories.

American health officials have warned that the spread of the impact of the Zika virus in the United States is far wider that they had anticipated. Anne Schuchat of the Center for Disease Control and Prevention said the virus has been linked to a broad range of birth defects and that pregnant women were vulnerable to contracting the disease for longer than previously thought. We absolutely need to be ready. Everything we look at with this virus seems to be a bit scarier than we initially thought. So we absolutely hope we don't see wide spread local transmit in the continental US. We need the states to be ready for that. We cannot assume we're not going to have a big problem. We know with other viruses we've had bigger problems and we expect it. So we're taking it very seriously.

Brazilian congressional committee is debating whether to recommend the impeachment of president Dilma Rousseff over allegations that she manipulated government accounts to hide a deficit. President Rousseff has denied the allegations and urges the allegations do not constitute a impeachable offense. A simple majority is needed to go to the next stage of voting the lower house of congress later this week. An opposition politician said the current government was paralyzed and that the impeachment was the only way forward. We hope the impeachment is important to Brazilian society and that we can have change. And with this change, we can really begin to look to the future and to the light at the end of the tunnel because this presidency, if it remains in power, it won't be in condition to govern. That's the tragedy of the administration we're seeing in our country today.
