• Britain should be a country that makes things. It's how we create good jobs, give more opportunities to young people, and build pride in our communities. That's why today’s announcement from McLaren matters. They’re backing Britain, keeping design, engineering and manufacturing here at home - with plans to build their engines in-house for the first time. Their £500m investment will drive growth far beyond their factory gates, creating a thousand jobs, supporting thousands more in the supply chain, and providing apprenticeships to young people. This is what reindustrialising Britain looks like.
