England head coach Eddie Jones has included five Leicester Tigers players in his squad for the start of the 2020 Guinness Six Nations.
Ben Youngs, with 95 caps, is the most experienced international in the squad and is joined by Tigers colleagues George Ford, Jonny May, Manu Tuilagi and Ellis Genge who were all part of the Rugby World Cup squad last year.
Jones includes eight uncapped players alongside 22 men who went to Japan last autumn in his 34-man selection who begin their preparations with a camp in Portugal this week.
Of the uncapped players Tom Dunn, Ben Earl and Ollie Thorley have been involved in previous England squads while Fraser Dingwall, George Furbank, Alex Moon, Will Stuart and Jacob Umaga are called up for the first time.
In addition, Josh Hodge and Alex Mitchell have been called up as apprentices and will train with the squad.
Jones said: “The Guinness Six Nations for us is all about raising the standards in terms of the way we prepare, tactically and physically how we play the game, and the way we come together off the field.
“But our first task is beating France in France and that is the only game we need to worry about. We will begin our preparations in Portugal, get a bit of sun, some warm conditions and get ourselves physically and mentally right for the game.
"The first three days will be about getting organised. We have got players from 11 clubs so we need to get everyone on the same page quickly, spend a lot of time working on our togetherness and then by Tuesday next week we are in Test preparation for France.”
The squad will assemble at Pennyhill Park on Wednesday and travel to Portugal on Thursday ahead of their first match against France in Paris on February 2.
The coaching team working with Jones and the squad includes attack coach Simon Amor and forwards coach Matt Proudfoot joining defence coach John Mitchell and skills coach Steve Borthwick.
