UK Foreign Secretary William Hague arrived in Baghdad on Thursday.
The Foreign Secretary appealed for politicians to put aside sectarian differences ahead of meetings with Maliki and other key figures, AP reported.
After touching down in the Iraqi capital, Hague said: “The Iraqi state is facing an existential threat, with huge ramifications for the future stability and freedom of this country.”
“The single most important factor that will determine whether or not Iraq overcomes this challenge is political unity,” he added.
“As a friend of Iraq, the UK believes the urgent priority must be to form an inclusive government that can command the support of all Iraqi people and work to stop Isis in its tracks.”
“The discussion of this key point is the purpose of my visit to Iraq and will form the basis of my conversations with Maliki and President of the Kurdish Regional Government Masoud Barzani as well as other key political figures.”
Maliki has already insisted that introducing an emergency administration would amount to a “coup against the constitution”.
