Not only ... but also.
//The Labour leader’s team invited dozens of advisers to an in-person Christmas bash in December 2020, in a move which would appear to have breached Tier 2 restrictions had it gone ahead. The event was later cancelled when London was placed into tougher Tier 3 restrictions, Politico reported today (Monday, May 9), but invites for the London party went out when indoor mixing between households was banned. An email was sent by the Keir Starmer’s office to Labour aides inviting them to the Christmas party on December 17, the news site claimed. A Labour source told Politico it would have seen a group of up to 40 people gathered at the same venue in separate groups of six. But the source said they declined the invite because they believed it would be a breach of the rules.//
Haha. An ex DPP who can't understand "the rules". Ever likely that the CPS was such a shambles when he was there.
