German Chancellor Angela Merkel has said that she doubted European leaders taking part in a summit this week on the EU's 2014-2020 budget would reach an agreement on the nearly one trillion euro spending framework. A day after the talks saw a rocky start with serious disagreements among officials in Brussels, Merkel said on Friday that another summit on the budget of the 27-country bloc would most likely be required at a later date, probably early next year.
