Guinea president Alpha Conde

Conakry, Guinea - A new political alliance in Guinea is signaling an erosion of support for the West African country's president.

The new alliance announced Friday is made up of members from two ethnic groups who backed President Alpha Conde during the 2010 election.

It was the country's first democratic vote since independence from France in 1958.

Guinea's president had promised to distribute administrative posts equally between members of his coalition.

Since coming to power, though, Conde is accused of favoring his ethnic group in appointments to government ministries, all the way down to the guards and janitors.

The latest defections come ahead of key legislative elections proposed for May. - Sapa-AP
