Supporters of Madagascar’s ousted government plan to launch a tax boycott to ratchet up pressure on the new authorities who seized power in a military-backed takeover last week.

The takeover, led by a 34-year-old former disc jockey, has been widely condemned by western donors on whom the Indian Ocean island is heavily dependent for financial aid. The new administration is also facing mounting street protests by activists demanding the return of Marc Ravalomanana, the toppled president.
