Princess Cruises has revealed its second round of celebrities who will speak on Southampton-based ship Sapphire Princess this year. The 2,670-guest vessel will head to northern Europe and the Mediterranean from May to October.

Further to the first round of celebrities who were announced in late 2017, the second group comprises:

· William Roache (actor, Ken Barlow in Coronation Street) on a 14-night Baltic Heritage cruise, departs June 2. His son, Linus Roache (actor, Michael Cutter in Law & Order), will also be onboard and fill a separate speaker slot

· Valerie Singleton (radio and TV presenter, Blue Peter, BBC Radio 4) on a 12-night Canary Island cruise, departs October 9

· Ann Widdecombe (former Conservative Party politician, Big Brother, Strictly Come Dancing) on a 12-night Canary Island cruise, departs October 9

· Terry Butcher (former football manager and England footballer) on a 14-night Baltic Heritage cruise, departs July 7

· Rosemary Shrager (chef, This Morning, The Real Marigold Hotel, Ladette to Lady, Soapstar Superchef) on a 14-night Mediterranean Interlude cruise, departs September 22

· Denny Seiwell (drummer and founding member of Wings) on a 14-night Land of the Midnight Sun cruise, departs August 18

· Allan Dennis Rich (songwriter, former Oscar, Grammy and Golden Globe nominee) on a 14-night Mediterranean Adventurer cruise, departs May 12

The addition of these speakers to the existing line up means at least one celebrity will appear on each Sapphire Princess sailing during the UK season, aside from a three-day Channel Islands voyage in October. They will host a 45-minute talk with questions and answers, as well as a meet and greet session including photographs and book signings.

Each voyage will also feature educational speakers who will discuss specialist subjects including history and culture, criminology, wellbeing and pop culture.
