ARLENE Foster has claimed there are "legal issues" surrounding Sinn Féin's allegations of corruption as part of the election campaign.
In recent weeks Sinn Féin has repeatedly made claims of "corruption, arrogance and contempt for whole sections of the public at the heart of government".
Numerous party election posters placed on lampposts call for people to "stand against corruption", and last Sunday the party launched an 'anti-corruption' billboard.
On BBC's The View programme, Mrs Foster was asked for the DUP's response to Sinn Féin's repeated allegation of 'corruption at the heart of government'.
The DUP leader said: "There's legal issues around that so I'll not get into that."
However, the DUP has refused to be drawn on the comments.
Asked yesterday to elaborate and whether it meant legal action was being taken, a spokesman for the party said they had "nothing further to add".
Sinn Féin also did not respond when asked if it wished to comment on Mrs Foster's remarks.
The election on March 2 was sparked by the political fall-out from the Renewable Heat Incentive scheme, which is now the subject of a public inquiry after running a projected £490m over budget.
