Straight off Wiki (every day's a learning day) : In March 2019, the European Research Group formed its own 'Star Chamber' to pass judgement on Theresa May's then proposed Brexit deal, and which recommended that MPs should not back it.[26][27] On 29 December 2020, the ERG's Star Chamber gave a similar verdict on Boris Johnson's recently agreed EU–UK Trade and Cooperation Agreement, but on this occasion recommending that their members vote for it because the deal is "consistent with the restoration of UK sovereignty". In December 2023 the ERG's Star Chamber rejected Rishi Sunak's proposed legislation to allow the Rwanda plan to go ahead.
