Nested Postgres Json Query

While using Json type in postgresql

data

---

{{"name":"Roy","Country":"USA","Hobby":"Swim"},{name:"Roy",Country:"USA","Hobby":"Crcket"},{"name":"Anam","country":"Greece","Hobby":"Polo"}}

how can i get all matching values with data->>name="Roy".

O/P should be : {{"name":"Roy","Country":"USA","Hobby":"Swim"},{name:"Roy",Country:"USA","Hobby":"Crcket"}}

How can i query for such condition ?
