The Labour Party - sponsored by PricewaterhouseCoopers? - Telegraph Chris Leslie, the shadow treasury spokesman, has become the latest in a growing list of Labour MPs to receive financial support from PwC, the accountancy giant that helps its clients avoid millions of pounds in tax. Leslie received the services of a senior manager at PwC for 30 days, which was worth almost £47,000. This brings the total given to Labour by PwC since the last election to more than £320,000. Ten members of Ed Miliband's opposition team benefit. The quango, which the Chancellor set up, even agreed that the optimal top rate of tax was precisely 45 per cent. Certainly, the Treasury's new head of spending, Sharon White, will be delighted to have the analysis in her first budget endorsed by this independent body. She will not have to go far to express her thanks, though. The head of the Office of Budget Responsibility is her husband, Robert Chote.
