Stormont Finance Minister claims efforts to link him to Nama controversy are 'petty party politicking'

Stormont's Finance Minister has insisted he knew nothing of a party colleague's controversial contact with a witness to an inquiry into the North's largest ever property deal.

Máirtín Ó Muilleoir said those seeking to link him to the controversy that forced the resignation of Daithi McKay, the former Sinn Féin chairman of the Assembly's Finance committee, were indulging in "petty party politicking".
