Revealed: Portillo's oil pay deal Michael Portillo faced intense pressure last night to reveal the full scale of his business affairs after leaked documents showed he was given secret payments by an oil giant. As calls for an inquiry into Portillo's earnings mounted, it was revealed that the shadow chancellor had only disclosed earnings of between £5,000 and £10,000 from the oil firm - and that this was 'only a small proportion of a wider agreement' between the two parties. A letter from oil exploration giant Kerr McGee - a copy of which has been obtained by The Observer - states that the cash Portillo is paid by the firm for 'parliamentary activities' is much smaller than his overall earnings for general advice. Portillo last night refused to disclose his overall income from the oil firm. The revelation will raise the question of cash for access, as Portillo, often regarded as the next leader of the Tory party, is the man responsible for setting Tory tax policy for oil companies. 'I'll be writing to the authorities and demanding a full investigation,' said Fraser Kemp, a senior Labour backbencher and close ally of Tony Blair. 'Mr Portillo is the shadow chancellor and responsible for making opposition policy on fuel taxes at a time when the industry's and his company's profits have gone through the roof. He must declare every penny he receives from this firm and the precise nature of the work he does for them.' Kemp said that Portillo's payments fromKerr McGee, the world's third largest oil exploration company, made his position 'untenable'. 'His constituents have every right to ask who he's spending his time working for - the people who elected him or the oil industry.' The letter was placed by Portillo in the Register of Members' Interests in the House of Commons. Signed by Frank Sharratt, the chairman of Kerr McGee, it states: 'You have worked for Kerr McGee between 1981 and 1983 and between 1997 and the present.' Although the letter says that the company 'rarely' asks Portillo's advice on British political issues, it goes on to say that 'we would not wish to preclude ourselves from ever receiving your advice on UK matters'. The letter, dated 26 January, 2000, states: 'We understand that you wish to register your remuneration for parliamentary services to us, which form a small proportion of a much wider agreement, and the remuneration for that part of our agreement is between £5,000 and £10,000.' Kemp said that the clear implication from the letter was that Portillo was in fact paid much more for the advice he gave the company. The letter reignites the row over Portillo's business affairs. The shadow chancellor was forced to make an embarrassing apology to the House of Commons last April when he admitted that he had failed to raise his connections with the firm when discussing fuel duty during the debate on the budget. A spokesman for Portillo said that he had registered everything that was necessary according to the rules of parliament. 'Mr Portillo is confident that he has complied with the rules of the house,' he said.
