It's all about infrastructure

The Chancellor could announce new taxes for tech giants like Amazon in today's Budget, analysts have said - but that could have knock-on effects.

As manager of East Midlands Airport, Karen Smart, points out, e-commerce has been very good for UK jobs.

The airport has been expanding rapidly because of its freight operation, driven in large part by a new distribution centre from Amazon.

"You can look out the window and see DHL, which has doubled the size of its operation, and UPS to my right with its large distribution centre of 700 acres," she told the Today programme.

"That’s going to double the number of jobs from 8,000 today to around 16,000 and even 20,000 by 2030, so it's really prosperous for the region".

So what does she want from the Budget? "What's really key in getting people to those jobs is improving the infrastructure... so local people can get to local jobs".

That means improving rail links long before the high speed network HS2 arrives.
