Carvalho was prime minister of São Tomé and Príncipe from 7 July 1994 to 25 October 1994 and again from 26 September 2001 to 28 March 2002.

[3] Carvalho finished second in the first round with 21.8 percent of the vote, behind former president, Manuel Pinto da Costa.

[4] In the July 2016 presidential election, Carvalho won the most votes but fell slightly short of a majority with 49.9 percent, so a second round runoff was held a few weeks later.

However, Costa, the incumbent president, withdrew from the 7 August runoff poll, alleging fraud in the July election.

Through their exemplary conduct, the people of São Tomé and Príncipe continue to serve as a beacon of democracy for other countries.
