[4][5] Sendov took part as an independent in the 1992 Bulgarian presidential election with Ognyan Saparev as his running mate, finishing in 4th place with 2.24% of the votes.

Although never a member of the BCP, Sendov had close ties to former Bulgarian communist dictator Todor Zhivkov.

The rightist Union of the Democratic Forces removed him temporarily from that duty in 2000 when Sendov cosigned, together with four members of the BSP, a letter to the Israeli president asking that portraits of the Bulgarian royal family (from the 1940s)[clarification needed] be removed from a memorial in Israel.

This memorial commemorates that all Bulgarian Jews were saved from deportation to concentration camps during World War II.

[4] In 2000 he was elected as a member of Serbian Academy of Sciences and Arts, an academic institution located in Belgrade, Serbia.
