Brasilia, May 9 (RHC)-- The acting speaker of the lower house of Brazil's Congress annulled the impeachment process against President Dilma Rousseff on Monday and called for a new vote in the chamber.

Waldir Maranhao, who took over as acting speaker last week, said there were procedural flaws in the April 17 vote in the chamber that accepted impeachment charges against Rousseff.

After last month's lower house vote, the impeachment process was passed to the Senate, where a Senate committee recommended on Friday that Dilma Rousseff be put on trial by the full chamber for allegedly breaking budget laws.

In a news release from Brasilia, Maranhao said the impeachment process should be returned by the Senate so that the lower house can vote again.

The full Senate had been expected to vote to put the Brazilian president on trial on Wednesday, which would immediately suspend her for the duration of a trial that could last six months. During that period, Vice President Michel Temer would replace her as acting president.
