British officials burned and dumped at sea documents from colonies that were about to become independent in a systematic effort to hide their "dirty" secrets, newly released files showed on Friday.

Under Operation Legacy, officials in Kenya, Uganda, Malaysia, Tanzania, Jamaica and other former British colonial territories were briefed on how to dispose of documents that "might embarrass Her Majesty's Government".

Newly declassified Foreign Office files reveal how the "splendid incinerator" at the Royal Navy base in Singapore was used to destroy lorry loads of files from the region.

Other officials wrote of documents being dumped "in deep and current-free water at the maximum practicable distance from shore", according to the documents in the National Archives.

One dispatch from Kenya in 1961 mentions the formation of a committee dealing with "'dirty' aspects of protective security" which would "clean" Kenyan intelligence files, according to The Times newspaper.

The British government agreed earlier this year to pay ยฃ14 million (16 million euros, $23 million) in compensation to more than 5,200 elderly Kenyans who were tortured and abused during the 1950s Mau Mau uprising against colonial rule.

The files released on Friday are the final batch of a collection whose existence was only revealed by the Foreign Office in January 2011 as part of the Kenyan action.

A Colonial Office telegram of 3 May 1961 stated the general guidance for keeping papers out of the hands of newly elected independent governments.

Items should be disposed of if they "might embarrass members of the police, military forces, public servants or others eg police informers; might compromise sources of intelligence" - or might be used "unethically" by incoming ministers.
