European Commission President Jose Manuel Barroso said the EU's executive arm will present proposals next week to step up the monitoring of bailed out nations as well as governments running excessive deficits. "We are indeed now facing a truly systemic crisis that requires an even stronger commitment from all and that may require additional and very important measures," Barroso told the European Parliament in Strasbourg, France. For countries that exceed the EU's deficit ceiling, the commission will propose on November 23 to give Brussels the power to review draft budgets before they are adopted by parliaments and even suggest amendments, he said. That could lead to friction with national parliaments. Barroso also said he would present proposals for the issuing of jointly-backed eurobonds, which Germany has opposed in the absence of meaningful pan-eurozone economic governance, by the end of the year. For his part, EU president Herman Van Rompuy told European MPs that he is considering a range of reforms to deepen eurozone integration from eurobonds to tougher sanctions on debt sinners and harmonised tax or social policy. "We need to acknowledge that this means a sharing of sovereignty for all members of the eurozone, and not only a loss for the countries in difficulty," he said in comments that could rile some member states. The European Council head said he would present ideas to a December 9 summit in key areas not all of which would require changes to the EU's treaty. These would examine whether to go beyond a set of laws already agreed to tighten budgetary discipline that are due to enter into force next month The ideas could include a call to institute "enhanced cooperation" across the 17 eurozone states. "In terms of deepening economic union, is there a need for harmonisation in certain areas such as taxation or even some social fields," Van Rompuy asked? "Should there be a limited mutualisation of public debt?" Van Rompuy said Brussels could be required to "intervene" in the drafting of national budgets, and said he would consider further sanctions for budget sinners, including the "suspension of voting rights and cohesion payments." That was a reference to EU grants to states for major infrastructure projects such as modern communications. Van Rompuy said talk that the drive to put in place a lasting solution to the debt crisis would create a "two-tier Europe" was "much exaggerated," and said it was "time to de-dramatise this debate." In recent days, German Chancellor Angela Merkel has said there was a need for "more Europe" and her government is pushing for more radical treaty change including ideas for the direct election of senior EU figures. British Prime Minister David Cameron, by contrast, has warned that he would use negotiations on changing the EU treaty to demand a repatriation of some powers from Brussels to London. Cameron faces a growing anti-EU backlash at home.
