Nusrat Ghani has become the first female Muslim minister to speak at the Commons despatch box.
Ms Ghani, who is the daughter of Pakistani immigrants, was promoted by Theresa May in last week’s reshuffle in which the prime minister tried to make her frontbench look "more like the country it serves".
The new parliamentary under-secretary at the Department for Transport has been Wealden MP since 2015.
And today she was cheered by parliamentary colleagues as she answered questions on access for disabled people at train stations.
Speaking about the milestone, Ms Ghani said it was an "important moment".
"As many people know, this year is also a significant milestone in this country, as 2018 marks 100 years of votes for women," she said.
"I hope that today, young people can see that regardless of their background, heritage or faith, there will be a warm welcome on the green benches – and no matter where you are from, you can achieve your dreams and ambitions.
"I am thrilled to be a minister at the Department for Transport, which is working hard to encourage more diversity in the transport sector.
"I’m excited to meet head on the opportunities and challenges that this new role this will bring."
Transport Secretary Chris Grayling said her promotion proved the Tories "were a party of opportunity", having produced the first woman prime minister as well.
"We’re the party to provide… the first Muslim woman minister to speak from the government dispatch box – the member for Wealden," he said.
"I congratulate her – I’m very proud to sit alongside her."
