The bizarre escapade provided a pretext for Myanmar's military regime to accuse Suu Kyi of violating the terms of her detention and to keep her out of the political picture for the next 18 months while it prepares for a general election next year.

Yettaw, 54, was sentenced to seven years in prison but was freed on August 16 at the request of visiting US Senator Jim Webb, chairman of the US Senate's East Asia and Pacific Affairs Subcommittee.

Webb, in a rare interview with Than Shwe, also requested that Suu Kyi be released but failed to secure the opposition leader's freedom.

Suu Kyi's ongoing house detention meant that it was unlikely that her National League for Democracy opposition party, which won the last polls in 1990 but has been denied power for the past 19 years, would participate in next year's election.

It also dashed hopes that prior to the polls, the regime might open a dialogue with the democracy icon and consider amending the 2008 constitution, which essentially cements the military's control over any democratically elected government.

Myanmar has been under military rule since 1962.
