England's ICC Women's World Cup campaign got off to a disappointing start as they suffered a one-wicket loss to Sri Lanka in Mumbai.
A half-century from Eshani Kaushalya and 62 from Chamari Atapattu saw Sri Lanka pass their target of 239 off the final ball.
Openers Atapattu and Yasoda Mendis (46) had got Sri Lanka off to the ideal start with a century stand - and although England's bowlers turned the screw in the middle overs Kaushalya then saw them home.
Arran Brindle, Georgia Elwiss and Katherine Brunt took two wickets apiece to give England hope, however Kaushalya remained defiant.
She finished on 56 off of 41 deliveries, with a towering six off Elwiss in the final over finally tipping the balance. And although Kaushalya was run out going for the winning run when the scores were tied, Dilani Manodara smashed the last delivery over the rope.
Earlier Jenny Gunn had scored 52 for the defending champions England as they recovered from a shaky start to post 238-8.
Chamani Seneviratna had struck twice in her first four overs as England slipped to 29-3, before Heather Knight (38) and Brindle (31) added 64 for the fourth wicket.
When they fell in quick succession, Gunn teamed up with 19-year-old debutant Amy Jones (41) in a stand of 83 to ensure the favourites recorded a decent total.
