Kyle Sinckler, the 24-year-old Harlequins prop who is yet to start a Test match for England, will be named as one of the ‘bolters’ in the British and Irish Lions squad when it is announced on Wednesday, The Telegraph can reveal.

Sinckler, who has made eight appearances off the bench since making his debut for England in the victory over South Africa last November, is poised to be named as one of six props when Warren Gatland, the Lions head coach, unveils what is expected to be a 37-man squad for the 10-match tour of New Zealand.

Sinckler is expected to be named ahead of more experienced tighthead props including Scotland’s W P Nel, Zander Fagerson and Wales duo Tomas Francis and Samson Lee and could be one of three surprise selections.

Sinckler’s England team-mate Ben Te’o, who has made just one start in his eight caps on the international stage, is also understood to be in strong contention for one of the five midfield berths.

Te’o, who was born in New Zealand and played rugby league for the South Sydney Rabbitohs and Samoa, qualifies for England via his mother and his strong ball-carrying made a significant impact off the bench as Eddie Jones’s side retained their Six Nations title.
