Prime Minister Sheikh Hasina is likely to fly for the UK on July 20 on a four-day visit to attend the first Girl Summit there.
The summit is aimed at mobilising domestic and international efforts to improve the lives of girls and women in the world's poorest countries.
Hosted by the UK government and UNICEF, the meeting will also help end early and forced marriage of girls, prevent violence against women, deliver their babies safely, get jobs, have education and supporting legal reforms to land and inheritance rights.
The Bangladesh PM will be touring the UK at the invitation of British Prime Minister David Cameron to join the summit in London scheduled for July 22, said official sources.
The invitation is considered important as the United Kingdom and other Western countries were critical of the January 5 general election, which was boycotted by major opposition parties and 153 candidates got elected uncontested.
Foreign ministry officials and Bangladesh High Commission in London are working out the details of the visit and trying to arrange meetings with British political leadership.
This would be the PM's fourth foreign trip since taking office for a second consecutive term. Hasina has already visited Myanmar, Japan and China.
The premier would arrive in London on July 21 and depart for Dhaka on July 23, said sources at Bangladesh High Commission in London.
The Girl Summit will aim to secure new commitments from the private sector, faith leaders, other civil society organisations and governments.
It will also share success stories and spread good practice in tackling the issues of early and forced marriage.
