The IMC was set up last week after 13 out of 15 members of AIBA's Executive Committee attempted a vote of no confidence against Wu during a meeting in Moscow.

The Guardian claims that since then, the four remaining members of the Executive Committee, absent in the Russian capital, have supported the motion.

Wu, elected President of AIBA in 2006 when he defeated Pakistan's Anwar Chowdhry, remains confident he retains support of the Member Federations.

If the 70-year-old Taiwanese receives the backing of the Federations at an Extraordinary General Assembly expected to take place in October he has not ruled out a bid for a fresh four-year term when his latest mandate ends next year.

Between now and then, the IMC believes it should have control of AIBA.

"We are taking legal action against President Wu in order to ensure AIBA funds are protected and are not abused," Canada’s Pat Fiacco, one of the officials listed as a member of the IMC, told The Guardian.

"We have asked the court to ensure the IMC can manage AIBA in the interim period until an Extraordinary Congress can be held, and that Dr Wu’s access to funds is blocked.

"We fear he may be using AIBA money to pay his personal legal bills.

"This whole process is about impeaching president Wu for what we believe is financial mismanagement of AIBA."

With the 2017 AIBA Men’s World Boxing Championships in German city Hamburg less than four weeks away, Fiacco said he hoped the decision by the Swiss courts would allow the IMC to bring stability back to AIBA.

"We have to ensure the Local Organising Committee in Hamburg and the German Boxing Federation feel they are getting the support they require," he told The Guardian.

Wu, also a member of the International Olympic Committee (IOC) Executive Board, rejected the contents of a letter sent to him by Italy's Franco Falcinelli, an AIBA vice-president and President of the European Boxing Confederation.

Falcinelli announced himself as chairman of the IMC.

Other officials listed as members of the Committee, on top of Fiacco, are Wales' Terry Smith, Morocco's Mohamed Moustahene and Cuba's Alberto Puig De La Barca.

Falcinelli claimed that the Executive Committee approved the formation of the interim group at the meeting in Moscow and are responsible for running the AIBA headquarters until October.

They have also sent a letter to all National Federations claiming they need a "clean start"... to "protect the future of our sport and organisation".

They dispute Wu's claim that he is a "volunteer" and accuse him of "travelling around the world in lavish personal style" and "collecting substantial funds from AIBA for personal use in his Taipei office".

"It is really important to say that we are following the AIBA Statutes throughout this process," Fiacco told The Guardian.

"The President does not have the almighty power to run AIBA."

The offices of AIBA are due to re-open in Lausanne tomorrow after being closed for a week. 

Police were called last week to intervene after both sides claimed control of AIBA headquarters on the Lausanne Maison du Sport International site.

"I will still be in charge [when the headquarters re-open]," Wu told insidethegames yesterday.

"I was elected by the AIBA Congress and only they have the power to remove me.

"I keep explaining this to the Executive Committee and tell them to read the Statutes.

"There is nothing in our constitution allowing them to set up an Interim Management Committee.

"It has no legal foundation."

insidethegames has contacted AIBA for comment.
