The invasion of the National Assembly
On August 7, the Department of State Services (DSS) blocked the National Assembly in Abuja.
The siege is alleged to be part of the plan to impeach the Senate President Bukola Saraki and his deputy Ike Ekweremadu. According to DAILY POST, the plan was to appoint then Ahmed Lawan as Senate President and Hope Uzodinma as his deputy.

After DSS operatives' invasion of the National Assembly, Vice President Yemi Osinbajo, who is currently the acting President (as M. Buhari had handed over power to Osinbajo while he was in London), sacked the Director-General of DSS Lawal Daura.

After the DSS invasion the National Chairman of the Peoples Democratic Party (PDP) Uche Secondus asked the United Kingdom to expel President Muhammadu Buhari from the country, alleging that it is Muhammadu Buhari who planned the siege. In his statement Mr. Secondus said the final plan for the invasion of National Assembly was made when the then Senate minority leader, Godswill Akpabio (left PDP for APC and subsequently resigned from the position of the Senate Minority Leader, on August 7), visited the president in London at the weekend.
Yemi Osinbajo stated that the siege was not authorised by the presidency.

However, on August 12, the Buhari Campaign Organisation (BCO) vowed to physically take over the National Assembly complex if Senate President Bukola Saraki does not resign from office.

During the inauguration of Ogun State secretariat of BCO in Abeokuta, the National Coordinator of BCO Danladi Fasali stated: "We, the Buhari Campaign Organization, are saying that the Senate President Bukola Saraki should take a bow and resign honourably. He should also be mindful of what happens and how senator Godswill Akpabio resigned because the position he was holding in the National Assembly is owned by the PDP, and immediately he leaves the party, he honorably resigns. We expect Saraki to do that. But, we are assuring him that BCO will take over the National Assembly if he continues to demonstrate his impunity. He lacks the sense of direction and he wanted to truncate the present democracy. We are assuring you that before their resumption date if nothing is done, the BCO will take over the National Assembly".
