I had read long back that Chanakya had discussed about the menace of corruption in his "Arthashastra" which was written around 2300 years ago. Britain was still struggling to start a civilization then. So I am sure the British were not the ones to introduce corruption to India.

The above link talks about how Kautilya(Chanakya), Kalhana and Ksemendra (both 12th Century AD) have discussed the issue.
