Creating a huge "emergency truck park" in Kent for up to 10,000 vehicles waiting to travel to Europe would be "bad news for British companies that have been through a terrible time," said Labor's Rachel Reeves .
Ms. Reeves said the country is "staring at the barrel of Brexit," only five months from the end of the transition period.
The Labor Brexit spokeswoman spoke to the PA news agency in front of a 27-hectare site near Ashford that was recently taken over by the government.
There were concerns that the country could be used as an "emergency truck park" for thousands of vehicles waiting to travel to continental Europe, and as border controls.
Construction work with heavy excavators was already underway behind Ms. Reeves.
