Charlotte Edwards took over as England coach at the start of last summer. After the preamble, it is time for England to get down to business. Having drawn a rain-affected 50-over series against New Zealand, coach Charlotte Edwards now has six T20s, starting with Wednesday evening's match against the White Ferns, to finetune her side before the World Cup begins on 12 June.

Edwards has been planning for this for months, but there remains plenty of questions to answer over the next two weeks before the big show gets underway. Tilly Corteen-Coleman is yet to win her first cap for England in T20 cricket.

When considering the bigger picture, the most significant part of the one-day international series against New Zealand was the arrival of 18-year-old spinner Tilly Corteen-Coleman on the international stage. That she looked so at ease on debut in Chester-le-Street, while able to admit she could have bowled better, was a major boost to Edwards, who has long talked up the spinner's talents.

Her emergence leaves Edwards with a difficult decision. Sophie Ecclestone, fitness permitting, still appears a guaranteed starter in England's World Cup XI, but who will join her in the spin attack? The other candidate is England's third left-arm spinner, Linsey Smith. Smith, a shorter, slingier spinner compared to the more Ecclestone-like Corteen-Coleman, was arguably England's best bowler at last year's 50-over World Cup and her skills of bowling in the powerplay – she bowled more than half of her World Cup overs with the new ball last autumn and took seven of her 13 wickets in that phase – are arguably even more relevant in T20s than ODIs.

It would be a big call to opt for the 18-year-old, but Corteen-Coleman has done her cause no harm. She took 1-18 in four overs in a T20 when 427 runs were scored during England's intra-squad camp in South Africa earlier this year. You could, of course, play all three left-armers, but that would probably mean leaving out vice-captain Charlie Dean and having a problematically long tail.

This is obvious, but is the most important question and impacts all of the decisions that follow. England have been managing playing time and various issues for a number of weeks – it is why many players skipped rounds of domestic cricket at the start of the season – but it will soon be crunch time.

The most significant is captain Nat Sciver-Brunt, who missed the New Zealand ODIs with a "minor" calf tear and has now been ruled out of the subsequent T20 series. England need her fit to play her full part as an all-rounder.

Ecclestone's appearance in the third ODI in Cardiff was only her fourth match of the season. She has been managing a quad issue which, again, England have said is only minor. Batter Sophia Dunkley, who is set to open with Danni Wyatt-Hodge at the World Cup, has only played once competitively since December amid a knee issue.

Then there is Issy Wong. The fast bowler was included on England's initial team sheet for the first ODI, only to be removed at the last minute because of hamstring tightness. She is fit to play in the T20 series against New Zealand, though, saying "it ended up being something very minor, but if I'd played on to try and get through that ODI it might have been different".

Even if everyone is fit, predicting England's T20 side requires some thought, given they have not played in the format since July last year. Maia Bouchier, Tammy Beaumont, Em Arlott and Paige Scholfield were in the XI for that defeat by India. None of those four are in the World Cup squad this summer.

Edwards has been boosted by the return of all-rounders Freya Kemp and Dani Gibson after injury. Former team-mate Katherine Sciver-Brunt says Edwards is "all about the all-rounders" in a hint at what could be ahead. "If you look at her teams it is her recipe for success," Sciver-Brunt, who is also married to captain Nat, said.

Gibson and Kemp were picked in unison during the New Zealand ODIs without making a real impact. Kemp is set to return to bowling in these matches, something she has not done in a competitive match since January 2025 because of repeated back issues.

If both are picked - Kemp has the benefit of being a left-handed batter who can clear the ropes when in form - it has a knock-on for the rest of the XI… 'A superstar in the making' - teen's journey from dog-sitting to World Cup. England's Kemp never considered future during injury woe.

If Kemp and Gibson, Ecclestone and Dean, plus one of Smith and Corteen-Coleman, are picked, that would likely mean there is only space for one frontline seamer in England's XI. That seamer will be Lauren Bell, should she remain fit and in form.

Bell has grown to become the leader of England's attack in the past 18 months and is one of the best pace bowlers in the world. Kemp, Sciver-Brunt and Gibson would provide back-up, but all three need to prove form and fitness in these matches against New Zealand and the three that follow against India.

Kemp would provide left-arm angle and Gibson, who only recently returned to bowling after a back stress fracture of her own, some bustle. England are expected to come through their group, which includes West Indies, New Zealand, Sri Lanka, Scotland, and Ireland, but would a specialist be needed if India or Australia await in a semi-final?

Dunkley, who scored a fine 102 from 51 balls in that high-scoring T20 in South Africa, Danni Wyatt-Hodge, who has scored two centuries and a 96 for Surrey this season, and former captain Heather Knight are other guaranteed starters in England's XI.

Unless England favour a batting-heavy approach and leave out one of those seam-bowling all-rounders, that leaves Alice Capsey, the breakout star of the early years of the Hundred but yet to find her place fully on the international stage, as the spare batter. Given Capsey is an off-spinning all-rounder, eyebrows were raised when Edwards confirmed the 21-year-old is the wicketkeeping back-up to Amy Jones in England's World Cup squad – a position Capsey has almost no experience in.

She was a keeper when coming through the ranks at Surrey but has only taken the gloves once in a top-level match. That was back in 2020 in a game for South East Stars against Southern Vipers in Brighton. England say Capsey has been doing wicketkeeping drills during their recent camps. They would also be able to replace Jones, who has an excellent fitness record, if her injury was serious.

Capsey would likely only be called upon to keep if Jones suffered a freak injury shortly before or during a game. Still, other England teams have fallen foul of poor prep in recent months. Do England need to give Capsey some experience with the gloves in an international before the World Cup comes around?
