BRUSSELS -- European leaders were drawing battle lines Thursday as they headed for a summit in Brussels, with France pushing back against Germany's call for a new czar with wide powers to veto countries' budgets.

In an address to Parliament ahead of the meeting, German Chancellor Angela Merkel endorsed a proposal for the EU's monetary affairs commissioner to become an enforcer of the bloc's budget rules _ including the power to refuse member countries' proposed budgets and send them back for changes.
