Does Lefebvre refer to the works of Anton Pannekoek, or is there any connection to German Councilists such as the KAPD?

As the title states, I'm looking for explicit or implicit references made by Henri Lefebvre to councilist thought. I know he essentially calls for a council movement in "The production of space." Similarly, I would be very interested if there are articles by the KAPD or Pannekoek (I'll even take KPD) that put forward ideas similar to the right to the city. Thank you guys for any and all help.
