The District Court in Lovech dismissed Desislava Ivancheva's request for conditional early release.
The decision can be appealed and protested within seven days before the Court of Appeal - Veliko Tarnovo.
The former mayor of the capital's "Mladost" district, Desislava Ivancheva, has been sentenced to six years in prison for corruption. She has a little more than a year left in prison to serve her sentence.
In February, the Supreme Court of Cassation ruled that the case for the early release from prison of the former mayor of the capital's "Mladost" district is within the jurisdiction of the District Court in Lovech.
Ivancheva began serving her sentence in prison in Sliven, but was transferred to Lovech.
