Prime Minister Sheikh Hasina's niece, Tulip polled 34,464 against her Conservative rival's 18,904 in Hampstead and Kilburn.
"I will be Hampstead and Kilburn's voice in Westminster, not Westminster's voice in Hampstead and Kilburn," she said.
Rushanara Ali, another Labour candidate of Bangladeshi origin, won Bethnal Green and Bow with 42,969 votes, beating her Conservative rival who secured more than 7,000 votes. Ajmal Masroor, an independent candidate of Bangladesh origin, finished the race with a paltry 3,880.
Rupa Huq, an academic of Bangladesh origin, also returned to parliament with a huge victory.
Rupa got 33,037 votes while her Conservative rival could manage only 19,272 in west London's Ealing Central and Acton constituency. The win widens her majority to a staggering 13,765 from a paltry 274 just two years ago.
Votes were still being counted in the snap election called seven weeks ago, with fears of a potential deadlock and a "hung parliament".
Tulip had resigned as a shadow minister in January to 'counter Prime Minister Theresa May’s Brexit from backbenches' after Labour leader Jeremy Corbyn decided to back legislation paving the way for the UK's departure from the EU.
After her victory in the snap elections, Tulip said she will keep an eye on Brexit negotiations due to start in just over a week.
Daughter of Sheikh Rehana, she was first elected to represent the constituency in the general election of May 2015.
