Meetings between former Home Secretary Charles Clarke and ministers from the largest EU states were criticised by an all party committee of peers today for a lack of transparency.
The House of Lords EU Committee warns the public have the right to know what goes on at the meetings which take place regularly with the ministers of the interior for the five other largest EU countries, Germany, France, Italy, Spain and Poland.
At the last meeting, in the Baltic resort of Heiligendamm in March 2006, the G6 Ministers discussed a joint response to terrorism, illegal immigration and organised crime. The UK was represented by then Home Secretary Mr Clarke.
Important decisions were reached, yet no report was made to Parliament and no publicity given by the Home Office.
Such meetings have been taking place since 2003.
The next, chaired by John Reid, is due in October.
The Lords committee said it accepts especially in an enlarged EU, it is inevitable and desirable for small groups of ministers to meet.
Lord Wright of Richmond, Chairman of the Committee said: "Parliament and the public, and other EU member states, have a right to be told what has been discussed and decided."
