"Credit to the Labour Party leadership for taking the bold step of giving Sikhs the opportunity to fight for winnable seats. Labour now needs to turn its attention to having visible Sikh representation in the House of Lords at the first opportunity so Sikhs are better represented and can bring fresh thinking and ideas," Sikh Federation UK said in a statement.
"Although it is early in terms of results declared this appears to be a disastrous night for the Conservatives and Theresa May given what she had hoped to achieve and a good night for the Labour Party. Labour is taking some important Conservative scalps," it added.
A second Sikh of the Labour Party Kuldip Sahota lost out to his Conservative rival by just 720 votes.

Among some of the prominent losses, Labour's Neeraj Patil the former mayor of the London Borough of Lambeth lost to Justine Greening, the UK's Education Minister.
He lost by a margin of 1,554 votes to Greening, who was defending her Conservative party stronghold.
Paul Uppal, who was expected to regain Wolverhampton South West for the Tories, also lost out to his Labour rival.
The Labour Party had selected 14 Indians and Conservative Party 13 as their parliamentary candidates.
So far, the tally looks stronger for the Labour Party with seven Indian-origin MPs to Tory's five.
The ruling Conservative party is on course to be the single largest party in the UK general election as many of the results and leads become clear in the ongoing count.
The projections indicate that the party remains shy of an overall majority, expected to win around 322 seats, down from the 2015 general election's 331 and short of the magic 326 figure for an overall majority in the House of Commons.
