The inquest into the deaths of Princess Diana and her boyfriend Dodi Fayed had cost British taxpayers nearly $5.8 million by the end of February, the coroner disclosed Thursday.

Nearly half of that amount has been spent for lawyers and other legal services. Spending for IT and video conferencing added nearly $2 million.

The final witnesses at the inquest, which opened on Oct. 2, testified on Tuesday.

The coroner, Lord Justice Scott Baker, intends to begin summing up the case for the jury on March 31.
