"A key part of this Government's strategy to create employment and growth in the economy is to ensure that we can build on our established base of world-leading technology companies," he said.

"This means ensuring that more and more dynamic and innovative international companies locate operations here, and ensuring that more indigenous companies start and expand on the back of their presence here."
