Sheffield MP Paul Blomfield will join the team holding the Government to account over the European Union in Jeremy Corbyn's shadow cabinet.
The Sheffield Central MP has been appointed shadow minister for Brexit in the team led by the new shadow secretary of state for Brexit, former director of public prosecutions Sir Keir Starmer.
Mr Blomfield said: "I've just completed my annual community consultation, the Big Conversation, meeting more than 1,000 people in 40 events across the city.
"Brexit was one of the issues raised most often, with deep concerns about the risks to jobs, the NHS and our universities.
"I'm delighted to have this opportunity to challenge the Government every step of the way to ensure that we get the best possible deal for our city and our country.
"Last week's Conservative Party Conference showed that, without any agreement among themselves, the Government is stumbling to disaster and it will be ordinary people who pay the price. I'm pleased to be part of a strong team that will hold them to account."
Other South Yorkshire MPs to join the shadow cabinet are Rotherham's Sarah Champion, who is now shadow women and equalities minister, and Sheffield Heeley MP Louise Haigh, who is part of the shadow culture, media and sport team.
