Mr Wineman and JLC chairman Mick Davis have not met since the row over the APPG but are due to sit in the same box at the new Chief Rabbi’s installation on Sunday.
A set of proposals known as the “Ten Propositions” was presented to deputies in June, which includes a new body consisting of two chambers, an elected president and a cabinet appointed by the president.
The next step is to appoint independent consultants who will be asked to glean the views of deputies.
Meanwhile, the JLC is yet to declare support for the new APPG. The JLC source said that “a decision will be taken only after the officers of the group are appointed, the level of parliamentary support becomes clear and the agenda of the group is spelt out”.
