Tarique Rahman is a leading figure in the opposition BNP
Bangladesh’s High Court has banned the media from reporting speeches and remarks by Tarique Rahman, eldest son of main opposition leader Khaleda Zia.
Mr Rahman, who lives in London, was earlier declared a fugitive after failing to return to Bangladesh to face corruption charges.
The ban extends to newspapers, radio, television and social media.
The move comes as Khaleda Zia continues to urge supporters to disrupt transport links in protest at the government.
Correspondents say there has been little impact.
The unrest comes on the first anniversary of disputed elections.
The vote – boycotted by the opposition who said it would be rigged – was won by the ruling Awami League.
Ms Zia remains confined by police to her offices in Dhaka for a fifth day. Her son is a leading figure in her Bangladesh Nationalist Party.
Ms Zia and her arch rival, Prime Minister Sheikh Hasina, have both frequently called for general strikes and blockades while in opposition.
The two women leaders have alternated in power for most of the last two decades when the army was not in government.
