David Cameron said it was not "right to reach back into history" to "seek out things we should apologise for" after he visited the Amritsar massacre site.
The Prime Minister, who expressed remorse for the atrocity, said:
In my view we are dealing with something here that happened a good 40 years before I was born, and we are dealing with something that ... the British government rightly condemned at the time.
I don't think the right thing is to reach back into history and to seek out things that we should apologise for. I think the right thing to do is to acknowledge what happened, to recall what happened, to show respect and understanding for what happened.
