Lloyds Banking could shock the market with its first-half results by announcing that accounting trickery has helped it scrape into the black. Despite enormous bad-debt provisions - estimated at £13bn - the bank is likely to post a modest headline profit for the first six months of the year. Some of its most toxic sub-prime investments have clawed back billions of pounds of value in recent months. Other credit instruments will also have recorded paper gains for Lloyds, the Sunday Times reports. Barclays is to pay tens of millions of pounds to its investment bankers, who have made huge profits from trading in government debt, derivatives and foreign exchange.

Traders are being offered at least one year's salary in cash as a signing-on fee, according to headhunters, the Sunday Times reports.Roger Jenkins, the executive who secured billions of pounds in overseas funding to help Barclays remain free from direct Government investment last year, is poised to leave the bank.

It is understood that an announcement could be made as early as this week, the Sunday Telegraph reports.Ron Sandler, the chairman of Northern Rock, has emerged as a surprise candidate to replace Sir Victor Blank at the helm of Lloyds Banking Group.

Sir Win Bischoff, the former chairman of Citigroup, and Chris Gibson-Smith, chairman of the LSE, are also candidates for the job, the Sunday Telegraph reports. George Osborne, the shadow chancellor, will this week publish his "white paper" on banking regulation, pledging to scrap the existing triparite system and the Financial Services Authority and hand back supervision to the Bank of England.

Thames, which supplies 13.6m customers in the South-east, has asked Ofwat to allow it to increase prices by 17.2% above inflation over the period to 2015, including a rise of about 10 % next year. Ofwat will publish its review of all public and private water companies on Thursday, the Sunday Independent reports.

Second-quarter GDP figures, to be published on Friday, are expected to show the economy shrank only slightly after its record six-monthly fall in the fourth quarter of last year and the first quarter of this year, the Sunday Times reports.The Sunday Independent adds that the UK economy is forecast to shrink by 4.5% in 2009 - the biggest fall in a single year since 1945.
