07.01 The illness of Antonis Samaras has also caused the the troika to postpone its visit to Athens, which was scheduled to begin today. 06.50 As we reported before the weekend, this week's EU summit has been hit by an untimely complication as the new prime minister and finance minister are unable to attend because of poor health. Antonis Samaras underwent eye surgery on Saturday and Vassilis Rapanos is in hospital after suffering from nausea. Instead, Greece's foreign minister and outgoing finance minister will attend the meeting, which takes place on Thursday and Friday. European leaders will discuss a cross-border banking union, closer fiscal integration and the possibility of a debt redemption fund. Greece will be asking for more time to complete its bailout reforms, while Germany will be doing all it can to resist. 06.46 Asian stocks have mostly drifted lower as investors grow cautious ahead of a critical EU summit later this week, where Greece will attempt to win some wiggle-room on the pledges it promised to enforce in return for its bailout. Japan's Nikkei 225 is 0.42pc lower and South Korea's Kospi has slid 1.11pc. 06.38 The Bank of England could be putting the economy at risk by persisting with low interest rates and money printing, according to the world's central banking supervisor. In an annual report spanning 214 pages, the Bank for International Settlements warned that artificially low rates and inflated asset prices could be holding back growth by masking lenders' bad debts and deterring them from cleaning up their balance sheets. Philip Aldrick reports: "Prolonged and aggressive monetary accommodation may delay the return to a self-sustaining recovery," BIS said. It can undermine the perceived need to deal with banks' impaired assets. Political pressure for loose monetary policy, including quantitative easing (QE), also threatened to damage central banks' credibility and destroy their independence, BIS said. The world's financial regulator spelt out the risks of relying too heavily on the likes of the Bank of England and other central banks as it pressed Europe's leaders to step up their efforts to fix the eurozone's problems. 06.34 Roger Bootle, who has been nominated for the Wolfson Economics Prize, writes in today's Telegraph that all the bailout systems under the sun cannot make the eurozone work: 06.31 Stop complaining and start doing. That was the frank message from Wolfgang Schaeuble, Germany's finance minister, to Greece yesterday, as he said the country should stop asking for more help and start work on implementing the reforms it has already promised. Alistair Osborne reports: In unusually blunt remarks, German finance minister Wolfgang Schaeuble said: "The most important task facing new prime minister [Antonis] Samaras is to enact the programme agreed upon quickly and without further delay instead of asking how much more others can do for Greece." His comments highlight Germany's growing impatience with the eurozone's problem nations in what is shaping up to be another significant week for the single currency bloc. Greece's new three-party coalition government took charge on Thursday, vowing to renegotiate the terms of its latest €130bn bailout. It wants a two-year extension to the 2014 deadline for it to cut its budget deficit to 2.1pc of GDP from 9.3pc in 2011. Such delay would, however, require up to €20bn more foreign funding.
