Kent Operation Stack solution 'vital'
Ministers need to justify their case for a "gargantuan" £250m lorry park put forward to ease disruption caused by cross-Channel services, MPs have said.
The Transport Select Committee said the decision to proceed with a 4,000-space park in Kent was taken "hastily" by the government.
It comes after part of the M20 was used 32 times last summer by queuing lorries - a process known as Operation Stack.
Labour MP Louise Ellman, chair of the committee, said it was vital a solution was found.
