The new arrangement to 2018 builds on an existing five-year agreement, which has kept the vessel ready for use by the Navy more than 99 per cent of the time.

Roger Bootle, a former government adviser who now works with Deloitte, the accountancy firm, predicted that 2011 would be the worst year for household finances since 1977 - and added that if interest rates were to rise, British families would not have seen conditions deteriorate so badly since 1952, the Independent writes.However, the Independent also reports that business confidence has rebounded by the strongest margin since May 2009, according to the latest Lloyds Bank Corporate Markets Business Barometer.

RWAs form the denominator of the key measure of banks' capital strength - the so-called core tier one ratio - with equity as the numerator, the Financial Times reports.A long-delayed report by the City watchdog into the collapse of Royal Bank of Scotland has hit a legal stumbling block. The Financial Services Authority is expected to admit defeat in efforts to publish its controversial report into RBS, which it had originally pledged to release in March. Taxpayers are still waiting to see the results of an investigation into what went wrong, including an examination of the behaviour of Sir Fred Goodwin and other top executives. Yet two and a half years after the banking crisis unfolded, sources close to the affair believe the draft report is still a long way from publication, reports the Daily Mail.
