Argentina vowed to press criminal and civil charges on British oil companies exploring off the Falkland Islands if they do not "justify their actions" by a May 2 deadline. In its latest escalation of rhetoric over the disputed islands, Argentina said it had written to Falkland Oil & Gas (FOGL), Borders & Southern, Rockhopper, Desire Petroleum and Argos Resources on April 17, to "notify them of their illicit actions and their consequences. In case of failure to offer a response and once the deadline expires, administrative sanctions will be imposed to each company within the framework of an Energy Secretariat resolution which deems these activities illegal. The Argentine government will also press criminal and civil charges," it said, according to The Telegraph. Motorists are facing the renewed threat of a crippling fuel strike after union leaders urged tanker drivers to reject the latest offer from their employers to end the long-running dispute. About 2,000 staff across seven separate firms have been told to turn down a peace deal aimed at averting industrial action. A meeting of union delegates voted "overwhelmingly" in favour of recommending rejection of the proposals. Eight days of talks had been held at conciliation service Acas to try to head off the prospect of strike action over issues including drivers' terms and conditions, pensions, and health and safety, The Scotsman reports.Business leaders have launched a robust defence of executive pay, claiming that the idea of a "cosy club" of directors patting each other's backs and setting salaries for one another is a "myth". In its submission to the Government consultation on improving transparency over executive pay, which closes on Friday, the Confederation of British Industry (CBI) said high pay is justified in return for excellent performance. The business group warned of misreading a widely-quoted survey from last year, which claimed chief executive pay had risen by 49% in just 12 months. The survey from pay consultancy Incomes Data Services, which used average figures, was "skewed" by very high salaries awarded to the very few, the CBI said, The Telegraph reports.Russian oil company Exillon Energy paid out nearly £1m on private jets, school fees and credit card payments for its former chairman Maksat Arip - but failed to disclose the payments. The money was used to fund Mr Arip's international lifestyle shuttling between Britain, Russia and Dubai, and for his children's private education. But it has emerged that the company executive who approved the payments could not speak English, and therefore apparently would not have been able to read the rules concerning the disclosure of payments to directors, none of which had been translated into Russian. A Financial Services Authority investigation has concluded that although there was nothing wrong technically in the company paying the cash to its former chairman but that Exillon should be censured for failing to disclose the payments, The Telegraph reports.Standard & Poor's has cut Spain's credit rating by two notches and warned that it is already considering a further downgrade, forecasting that the country's economy would contract for the next two years. "Spain's budget trajectory will likely deteriorate against a background of economic contraction in contrast with our previous projections," the credit ratings agency cautioned. S&P also said that it saw an increasing likelihood that Spain's Government would have to take on more debt in order to support its banking sector. As such the agency has downgraded Spain to BBB+ status from A and immediately put a negative outlook on its new rating, citing "significant risks" to the country's economic growth and budgetary performance, The Times says.
