Plaid Cymru leader Adam Price has criticised Welsh Labour for not being "proactive enough" when it comes to preventing job losses in the manufacturing sector.
On the campaign trail in Ystrad Mynach on Monday (3 May), Price visited car parts firm Kautex Textron, where 200 jobs are at risk.
The firm makes hoses, water containers, and nozzles for the automotive industry.
In April, Kautex, which has had a site in Ystrad for money than 50 years, announced that it was considering closing the factory due to the economic impact of Brexit and Covid.
Price condemned Labour's alleged inaction, saying: "They should be in there talking to these companies in the Welsh manufacturing sector, that are facing a bit of a perfect storm at the moment with Brexit and Covid, in order to identify where the threats are."
Price said that Labour was guilty of having "one economic plan", which consists of luring in foreign companies rather than investing in "homegrown businesses".
Price said: "It's all been about just looking to salvation from companies coming in from outside, that's not going to build the economic foundation for the future.
"We've got to shift the focus from just relying on foreign-owned companies coming in for a while - we've got to invest in our own homegrown businesses."
