When I went to Southall on Monday morning it took me only six minutes to drive from West Ealing to the Herbert Road MSCP arriving at 9:39. It took 10s to park. There were so few cars in the car park that I was able to count 22 spaces occupied out of 270.
The Labour group will tell you that the new car parks in Southall are needed to support the weekend trade. The trouble is that car parks cost you money 24/7. If the new car parks are empty most of the time then they are simply unaffordable. It is hard to see how you justify a business case for any new car parks in Southall.
