Concerns have mounted as a proposal by a Bank of England adviser, calling for the doubling of new internationally agreed capital ratios, appears to have gained ground.

The electricity generating industry has warned the Treasury that it has gone too far, too fast by implementing a carbon price floor in last week's Budget, claiming that the tax could also kill off plans by coal-fired power stations for futuristic and expensive carbon-capture schemes., the Times reports. Extremely high levels of radioactivity have been de¬tected in a building beside the No 2 reactor at Japan's stricken Fukushima Daiichi nuclear power plant.

Ford is the latest car giant to cut production as the industrial fallout from the Japanese earthquake and tsunami ripples through the global automotive industry. The US company said at the weekend that it will idle its factory in Genk, Belgium, for five days in early April, to conserve supplies of parts shipped from Japan.

Described as "angel investors" because of their generosity in helping start-up companies, the 39 signatories include influential figures behind recent successes such as Lovefilm.com and Zoopla, the property website.
