The controversy over whether or not the Prime Minister owns Egrant, the secret company in Panama, was reduced to a joke on Wednesday by the former Pilatus Bank employee who made the claims in the first place.

Maria Efimova, who had made the claims to journalist Daphne Caruana Galizia, uploaded a tweet showing her dancing with two other women and challenging Joseph Muscat to 'dance battle'.

'Whoever loses, owns Egrant,' she wrote.

A dance battle involves two people taking it in turns to dance in front of an audience or panel of judges, who then decide which of the contestants has danced best. 

A magisterial inquiry into Ms Efimova and Ms Caruana Galizia's Egrant claims had concluded in the summer that there was no evidence that Dr Muscat or his wife owned the company.  

Ms Efimova has successfully resisted efforts to be extradited to Malta from Greece to face court proceedings instituted against her by Pilatus Bank.
