The Commons' charge was led by British-Pakistani Sajid Javid, the Conservative party's first Muslim cabinet minister, who served as culture, media and sports secretary in Prime Minister David Cameron's first Cabinet.
Javid, whose father arrived from rural Pakistan in the 1960s and worked as a bus conductor and driver in the UK, was re-elected as Bromsgrove MP with huge 28,133 votes.
"Voters have supported the Conservatives as they did not want to see the economic recovery put at risk," he said after his win.
However, it is the Opposition Labour which has scored the most wins - Yasmin Qureshi from Bolton South East, Shabana Mahmood from Birmingham Ladywood, Khalid Mahmood from Birmingham Perry Bar, Imran Hussain from Bradford East, Sadiq Khan from Tooting and Naseem Shah who caused one of the biggest upsets of election night by defeating favourite-to-win Respect Party MP George Galloway in Bradford West.
