Summarize on one column but select another column

Hi PranjalSaxena - Can you try the below calculated table in your model.

WinnerParty =
ADDCOLUMNS(
SUMMARIZE(
VotingResults,
VotingResults[State],
VotingResults[Constituency],
"Max Votes", MAX(VotingResults[Votes])
),
"Party",
SELECTCOLUMNS(
TOPN(
1,
FILTER(
VotingResults,
VotingResults[State] = EARLIER(VotingResults[State]) &&
VotingResults[Constituency] = EARLIER(VotingResults[Constituency]) &&
VotingResults[Votes] = EARLIER([Max Votes])
),
VotingResults[Votes],
DESC
),
"Party", VotingResults[Party]
)
)

It works please check.
