The head of Systmebolget, the Swedish alcohol monopoly at the centre of a corruption scandal, and the country's Prime Minister are planning to marry, a aid was reported to have said today.

Prime Minister Goran Persson and Anitra Steen made their relationship public in February and moved in together in July.

A date for the wedding is not yet known.

The relationship has come under scrutiny from some areas, who claim it presents potential conflicts within government, particularly as the investigation into the scandal continues.
