A group of economists has written to the Queen urging her to demand monthly ministerial briefings on possible pitfalls looming for the economy. Responding to her concern over why no one foresaw the recession, first voiced in a visit to the London School of Economics last summer, the letter suggests she might play her own role. 'If you, your majesty, were to ask for a monthly economic and financial horizon-scanning summary from, say, the cabinet office, it could hardly be refused,' said the letter, signed by LSE professor Tim Besley, and historian Peter Hennessy

European leaders gathered in Brussels on Thursday for a summit devoted to economic policy amid growing speculation that they could come to Greece's rescue in the first bailout by the eurozone of a single-currency country. The European Central Bank signalled that its head, Jean-Claude Trichet, had cut short a trip to Australia to rush back to Brussels for the summit, triggering speculation that the 16 eurozone countries were preparing a bailout for Greece, which is teetering on the brink of national insolvency.

Public sector workers in Greece took to the streets during a nationwide one-day strike in protest at the austerity measures being implemented to try to address the country's financial crisis. Anger in Athens started with graffiti and by dawn the calls to battle were daubed across the facades of banks and shops and government buildings. By noon it had morphed into a 'resistance movement' as militant leftwingers and striking civil servants – some holding banners, some pounding drums, some shouting themselves hoarse – marched

Hats off to the Bank of England's governor, Mervyn King, who found the time to go for a ride on a dog sled during the weekend's summit of G7 finance ministers, which Canada hosted in the remote Arctic city of Iqaluit. Other local customs were less popular: none of the visiting ministers chose to attend a feast on Saturday night, laid on by the local Inuit community, at which raw seal was on the menu. Canada's Jim Flaherty was left to chow down on some seal meat alone

Many of Britain's towns and cities are suffering from such huge shop vacancy rates that they risk becoming ghost towns, wiping hundreds of millions of pounds off property values, a study revealed this week. Cities such as Wolverhampton and Bradford (pictured), where nearly a quarter of shops lie empty, could be on an irreversible downward spiral as a result of the financial crisis. The research by the Local Data Company shows retail vacancy rates across Britain rose 2% in the past six months of last year to 12%, with some towns seeing as much as 24% of its shops lying empty

Sir Richard Branson and fellow leading businessmen warned ministers that the world is running out of oil and faces an oil crunch within five years.
