Prime Minister Sheikh Hasina on Monday said ‘Joy Bangla’ has got recognition of the national slogan proving that no sacrifice goes in vain. “Today the ‘Joy Bangla’ slogan is for all, the people of this country, the victorious nation and the Bengali nation…… It has proved that no sacrifice goes in vain,” she said  The prime minister was addressing a programme titled ‘Joy Bangla’ at a city hotel, virtually from her official residence Ganobhaban. Bangladesh Association of Banks (BAB) arranged the programme to mark the announcement of ‘Joy Bangla’ as the national slogan.  Hasina said Bangabandhu concluded his historic 7th March speech by chanting the ‘Joy Bangla’ slogan that means he had been quite sure that Bengalis would gain victory.

But the people who belong to Awami League or followers of the ideology of Bangabandhu, freedom fighters and believers in the spirit of liberation war upheld the slogan, she said. “Obstacles came. We had to hear many insulting words and face various criticisms. Since we’ve been able to keep up this true (words) even after these, it has been recognised as the national slogan today,” said the PM.  She said this slogan had helped achieve the victory by inspiring the people of the country to sacrifice their lives. “Inspired by this slogan, the people had written with blood that they wanted to achieve victory,” she said.  "With this ‘Joy Bangla’ slogan, we want to reach it (message) to the people of the world that we are victorious nation, we gained the victory, we don’t move downing our heads, and every Bengali will move raising head, no matter where he or she stays,” she said. Talking about the difficult days after the 1975 assassination, Hasina said had her younger sister Sheikh Rehana, the only other survivor, been beside her in the function, she would have been very glad. “She (Sheikh Rehana) is a big strength for me,” the PM added.
