The Christian charity voiced its concerns at the United Nation's latest Commission on the Status of Women (UNCSW), which is the principle global intergovernmental body exclusively dedicated to the promotion of gender equality and the empowerment of women.
Rose Wright, campaigns and social policy manager at Mothers' Union, attended the event and said that it is government's responsibility to ensure women's rights are continually fought for.
Wright told Premier: "Obviously, there are lots of issues going on in the world but we have seen in the recent year, a real back-slide by particular governments and regimes in terms of their legal protection for women as well as funding for women as well".
While she believes various governments over recent years in the UK have made progress with issues surrounding female empowerment, she said the next elected government needs to do more.
"In the UK we're at a very critical moment. We're facing a general election.
"We're looking at exiting the European Union. So it's a critical time for whichever government arises on 8th June to continue to promote women's empowerment.
"The key thing is the implementations of different laws that have been made.
"For example, we've seen the introduction of a new law which allows a certain amount of leave to be taken after a child is born and can be split whichever way is appropriate between a mother and father.
"In the UK we've seen the take-up of that is very low - it's between two and eight per cent. In countries like Sweden we've seen the take-up of that is around 85% so the UK still has a long way to go."
The 61st session of the UNCSW took place at the UN's headquarters in New York from 13 to 24 March 2017. The agreed conclusions negotiated by all States urged governments at all levels, the general public and the private sector to address women's economic empowerment in the changing world of work.
