"His form warrants it," Southgate said. "We like what we've seen in terms of his personality, his character, and his leadership qualities. He'll fit very well into how we work."
Earlier this month, FIFA approved Rice's eligibility to represent the Three Lions after he appeared in three friendly matches for the Republic of Ireland last year. Rice, who was born in London, was eligible to play for Ireland via his paternal grandparents.
While Rice has been rewarded for his play at West Ham, the likes of Aaron Wan-Bissaka, James Ward-Prowse, and Conor Coady will be disappointed to miss out on representing England after performing admirably for their respective clubs.
"We love Prowsey - this recent spell is his best since we capped him and he's a world-class set-piece taker, but he's only recently got back in the team at Southampton," Southgate said when asked about Ward-Prowse's absence
Additionally, teenager Jadon Sancho received his second consecutive call-up following continued positive performances at Borussia Dortmund, while Callum Wilson was also selected again after scoring in each of Bournemouth's last three Premier League matches.
