According to the documents, the party’s pollster BMG Research had organized a focus group that tested two increasingly popular lawmakers from the party — Shadow Education Secretary Angela Rayner and Shadow Business Secretary Rebecca Hall — for potential succeeding Corbyn. The two were reportedly considered as the most likely candidates for leading the party.
The focus group's test showed that Corbyn himself was seen as "boring" and that the Labour leader "looks like a scruffy school kid", the documents, cited by the media, said.
After the Brexit referendum in June 2016, members of the Labour Party, which had called on the UK citizens to vote for remaining in the EU, have already tried to issue a motion of no confidence in their leader, but Corbyn managed to win.
