Prime Minister David Cameron directed his Cabinet Secretary Jeremy Heywood to probe the facts behind claims of British collusion in the operation that emerged as part of recently declassified documents.
Britain's only Sikh MP, Paul Uppal, outed a meeting with Heywood on the issue, triggering questions over why only the Conservative Party politician was being allowed access.
"It is important we take the politics out of this...But I have wanted to go and see the people right at the centre of this to impress upon them how important it is that we move urgently and we get to the truth," Uppal said.
It prompted coalition partners Liberal Democrats and Opposition Labour MPs to demand a meeting with Heywood.

Uppal, who eventually met the Cabinet Secretary with former Labour business minister Pat McFadden, told the 'Guardian': "As the only Sikh MP it was only reasonable and sensible that I should go and see the Cabinet Secretary. I got an invite. I had been pushing for it. I made it clear I wanted to see the Cabinet Secretary."
McFadden said, "No one should underestimate the degree of pain which still exists in the Sikh community about these events (in 1984) partly because of the belief that the full truth has never been told.
A set of letters released by the National Archives earlier this year had indicated that Britain's Special Air Services (SAS) commandos may have been involved in training the Indian Army for the operation to flush out militants holed up in the Golden Temple.
Cameron was forced to issue a statement in Parliament, stressing that "the inquiry will be thorough, transparent and will get to the truth".
