Gareth Southgate managed England between 2016 and 2024

Former England manager Sir Gareth Southgate says he is "worried about unity" amid a debate about flying the St George's flag.

A growing number of St George's and union jack flags have appeared across England in recent months.

While some people feel the flag-raising is patriotic, others feel it is intimidating.

Southgate, who spent eight years in charge of the Three Lions, stepped down as manager following a Euro 2024 final defeat by Spain.
