But one of his communication advisers is Rob Allyn, an American political consultant has who worked for George W. Bush and Mexico’s Vicente Fox among many others.

Management consultants at McKinsey say the Indonesian middle class consists of 45m people, while their rivals at Boston Consulting Group cite a figure of 74m. The Asian Development Bank puts it at an eye-popping 146m, or 59 per cent of the population.

Either way, investors are whetting their appetites at the prospect of selling their goods and services into this undoubtedly large and fast-growing market of consumers. Read more

While the “quick count” results from Wednesday’s five-yearly legislative election are only preliminary, it seems clear that the Indonesian Democratic Party-Struggle (PDI-P) has failed to fully capitalise on the popularity of its presidential candidate, Joko Widodo.

Having named Widodo, the highly regarded Jakarta governor, as its presidential candidate in March, PDI-P was targeting at least 27 per cent of the vote for the 560-member House of Representatives (DPR). But initial results showed that it secured 19 per cent, in spite of coming first.
