Maulana Rafiqul Islam Khan, Assistant Secretary General of Jamaat-e-Islami and newly elected Member of Parliament from Sirajganj-4 (Ullapara), has been appointed as the opposition whip. The announcement was made to the media following a meeting of the opposition parliamentary party after members took their oaths.

Rafiqul Islam Khan won the election under the 'scales' symbol with 161,872 votes, narrowly defeating BNP candidate M. Akbar Ali, who received 161,278 votes under the 'paddy sheaf' symbol. This marks Rafiqul’s first term as an MP, achieved by a margin of only 594 votes.

In the 2018 election, Rafiqul contested under the BNP alliance using the 'paddy sheaf' symbol but lost to Awami League candidate and freedom fighter Shafiqul Islam Shafi. His current appointment as opposition whip follows his first parliamentary victory.
