Did strike me earlier that 2023 is a perfect opportunity for the Cmme to utterly smash their record if they wanted to.
The likely holdovers from 2022 are either notoriously old (Kissinger, Carter), ill (Charlton, Starmer-Smith, Pele, Whale), or known frail people (Tebbit).
The potential returnees include Joanne Woodward (very ill for a decade), Linda Nolan (Stage IV cancer), Pope Benedict (looks like a corpse), Willie Nelson (seriously ill earlier this year, and 90 next year), Nigel Lawson (last legs for ages now), and Liza Minelli (very badly il at the Oscars)
Gravely ill people who feel very DLy include George Alagiah, Ryuichi Sakamoto, Frank Field, Rolf Harris, Roberta Flack, and Johnnie Irwin. Not been so many "yeah they're obviously DL" dying names to my mind since 2009.
Ill folk they could easily go for include Andy Taylor, Frank McGarvey, Steve McMichael. (I dont care about your fame thoughts, they picked Bill Gate's dad, case closed.)
Then there's your frail/sick/just old names who feel DLy: Fay Weldon, the Duke and Duchess of Kent, David Graham, William Russell, Pat Robertson, Sandra Day O'Connor, Dennis Skinner, Topol, Ruth Buzzi, Sonny Rollins, etc etc.
Def feel like over 20 is possible with a great, well chosen, list.
