Candidates backed by President Luiz Inacio Lula da Silva are elected as leaders of Brazil's Chamber of Deputies and Senate in a tightly guarded ceremony, less than a month after rioters invaded Congress, the Supreme Court and the presidential palace. In a win for veteran leftist Lula, Rodrigo Pacheco held onto his post as president of the upper house of Senate, fending off a challenge from a rival supported by far-right ex-president Jair Bolsonaro. The lower house leadership vote was won by a record 464 ballots by incumbent speaker Arthur Lira, a key figure in a loose coalition of parties dubbed the "Centrao". IMAGES AND SOUNDBITES
