Pro40
former one-day cricket league in England
The NatWest Pro40 League was a one-day cricket league for first-class cricket counties in England and Wales. It was inaugurated in 1999, but was essentially the old Sunday League retitled to reflect large numbers of matches being played on days other than Sunday.
Sunday League
The Sunday League was launched in 1969, as the second one-day competition in England and Wales alongside the Gillette Cup (launched in 1963). Sponsored by John Player & Sons, the league was called John Player's County League (1969), the John Player League (1970–83), then the John Player Special League (1984–86). The 17 counties of the time played each other in a league format on Sunday afternoons throughout the season. These matches were concise enough to be shown on television, with BBC2 broadcasting one match each week in full until 1980, and then as part of the Sunday Grandstand multi-sport programme. For close finishes for the title, cameras appeared at the grounds where the contenders for the title were competing and the trophy presentation to the victorious team would be on film.
Refuge Assurance replaced John Player Special as the sponsor of the competition, called the Refuge Assurance League, in 1987. In 1988 they introduced an end-of-season play-off competition known as the Refuge Assurance Cup. The top four teams of the league season qualified for this competition, with the first-placed team playing the fourth and the second-placed team playing the third, and the winners of these matches meeting in a final at a neutral venue.
This brief starts where responsible research should: with the source description of “Pro40” as former one-day cricket league in England. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as former one-day cricket league in England. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 31, 2025. The linked authority identifier is Q1967413. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1999, 1969, 1963 and 1970.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
