The president’s term officially ended at midnight on Thursday.
However, instead of transitioning power, Embalo has remained in office, an action the opposition deems an unlawful power grab.
Embalo has pledged to continue fulfilling his presidential duties until the elections on November 23rd, with many speculating that he will seek a second term.
Experts are now raising concerns about the potential for a constitutional crisis and political instability.
According to Guinea-Bissau's constitution, the presidential term is five years, with a limit of two terms. The opposition argues that Embalo’s term should have concluded on February 27th, but the country's Supreme Court ruled it should extend until September 4th.
In recent months, the opposition has refused to recognize Embalo as president.
Additionally, elections for a new parliament have not been held since the previous assembly was dissolved in 2023.
Guinea-Bissau, a small West African nation, has faced numerous coups since gaining independence from Portugal over 50 years ago.
A West African regional bloc mission sent to mediate the crisis in March left abruptly after Embalo reportedly threatened to expel them.
