Heidi Alexander has replaced Louise Haigh as the new transport secretary.
The Swindon South MP was previously justice minister and also worked as deputy transport mayor under Sadiq Khan between 2018 and 2021.
She takes over from Haigh, who resigned after she admitted pleading guilty to a fraud offence.
Haigh was convicted of falsely telling police her work mobile phone had been stolen during a mugging in 2013.
Commenting on the new appointment, RHA MD Richard Smith said: “On behalf of the RHA, I’d like to congratulate Heidi Alexander MP on her appointment as the new transport secretary. We look forward to working closely with her on the important issues facing our critical industry.
“HGVs, vans and coaches play a pivotal role in the supply-chain and the daily life of businesses across this nation - moving goods and people every day. We’re also crucial to the government’s stated objective of boosting economic growth.
“We look forward to working collaboratively with the transport secretary and her ministerial team on solutions to improve roads, infrastructure and driver facilities on the decarbonisation journey in the months and years ahead,” he added.
The chartered institute of logistics and transport UK (CILT UK) said it also welcomed working with the new transport secretary to develop sustainable, efficient and passenger-focused solutions across the sector and to support the wider supply chain.
