The sexual abuse scandal has so far cost the Dutch Catholic church over €8m in research costs and compensation payments to victims.

Most of the money has gone on the massive research project led by Wim Deetman into the scale of the problem.

The report, published in 2011, concluded at least 800 Roman Catholic priests and monks were involved in abusing children in their care between 1945 and 1985.

In total, €3m has been paid in compensation to victims, according to the Church’s annual accounts and quoted by news agency ANP. It is the first time the church has published its annual accounts and the figures cover 2012, ANP says.

The report also shows the Church is in financial difficulty in the Netherlands and made a loss of €4.3m in 2012, partly due to declining income from individual churches.
