The group also faulted the 1964 population census, which it said was falsified to give the North edge over the South.
The British government has been accused of fueling unrest and political tension in Nigeria.
The Indigenous People of Biafra (IPOB) stated this yesterday while advising British High Commissioner Catriona Laing to distance herself from Nigerian politics and political processes.
The group also faulted the 1964 population census, which it said was falsified to give the North edge over the South.
In a statement by IPOB Media and Publicity Secretary Emma Powerful, the body noted that the British government contributed 99.9 per cent of the political problems facing the country.
Also, residents of Abia state have cleared the air after observing sit-at-home yesterday.
Residents who observed sit-at-home order yesterday said they didn't do it in obedience to the order by Simon Ekpa.
Ekpa had ordered Southeast people to observe sit-at-home for five days as part of their efforts to push for the release of the detained leader of the group, Nnamdi Kanu, who is in the Department of State Services (DSS) custody.
Residents of Aba, the commercial city of the state and their Umuahia counterparts, stayed away from their shops and offices yesterday as they continued to observe the Monday sit-at-home.
Major markets, banks and other public institutions were closed for business, but some private schools, which were yet to close for the year, used the day to hold their Christmas parties.
Some of them, who spoke to TheNation, said their compliance with the sit-at-home was not in obedience to the order of Ekpa.
They said it was insensitive of Ekpa to call for a five-day sit-at-home in the Southeast without any good reason.
TheNation reports that commercial motor parks were opened for business.
There was no harassment of residents by any person or group of persons.
