By 2007, Ranvir was promoted and became a co-presenter with Gordon Burns. She became a familiar face on the award-winning show; she won the prize for ‘Best Regional On Screen Talent’ at the Royal Television Society's North West Awards in 2010. Combined with regular presenting roles on BBC Radio 5 Live breakfast shows and phone-ins, she covered everything from major sporting events abroad to political fracases at home.
After the birth of her son, Ranvir made the decision to move from the North West to London to work for ITV. In 2012, she joined the new morning news programme Daybreak, now Good Morning Britain, and is a major part of their team. She covers a wide range of national and international news and she counts her most memorable moments so far as having been reporting ahead of the G20 from Sierra Leone's slums, appearing on the University Challenge Christmas special and meeting Kermit the Frog.
In 2020 she took part in BBC One’s Strictly Come Dancing. Alongside her role as Political Editor for ITV’s Good Morning Britain, Ranvir also presents 'Eat, Shop, Save' for ITV and occasionally presents Lorraine.
