As head of the richest European economy, German Chancellor Angela Merkel has been variously called the Paymaster or even the Queen of Europe.
But fancy titles will mean nothing in Berlin tomorrow, when Merkel has to somehow find a path between two crushing forces - electoral hostility and market scepticism - in a vote likely to determine the path of Europe's financial crisis.
Merkel is asking the Bundestag, the Lower House, to endorse a plan to pump a further €190 billion ($327 billion) into a €250 billion rescue fund to support the eurozone's biggest debt-stricken economies.
Had the vote taken place a few months ago, Merkel would have walked it. But her public standing has slumped just as Germany's bill for bailing out Europe's spendthrifts has risen. Her party, the conservative Christian Democratic Union (CDU), has lost six out of the seven regional elections this year and is squabbling with its coalition partner, the pro-business Free Democratic Party (FDP), which is saying in essence: "Enough's enough."
At the same time, Merkel is facing mounting pressure from global markets to further strengthen the rescue mechanism, known as the European Financial Stability Fund, or EFSF. After a meeting of the International Monetary Fund in Washington at the weekend, stock values rose sharply amid expectation that a doomsday save-the-euro strategy was in the works and that the EFSF would rise to €2 trillion.
