Burmese democracy icon Aung San Suu Kyi made a historic addresses to Britain's parliament Thursday, following an earlier meeting with Prime Minister David Cameron.

The Nobel laureate's speech at the historic 11th century Westminster Hall came during her first trip to Britain since leaving the country 24 years ago to lead Burma's pro-democracy movement.

Aung San Suu Kyi said this is the time to re-establish a true democracy in Burma, adding that if things are not done correctly, it may be decades before another opportunity arises.

Aung San Suu Kyi commended the reforms taking place under President Thein Sein, but said “without strong institutions, the process will not be sustainable.”

She called on Britain to consider what it can do to help build the institutions needed to support the country's parliamentary democracy.

Aung San Suu Kyi, who spent much of the last two decades in detention under Burma's former military rulers, met earlier with Mr. Cameron at his official residence at 10 Downing Street.

The two last met in Burma in April, when Mr. Cameron announced the lifting of sanctions against the Southeast Asian country in recognition of its recent political reforms.

The British government announced Thursday that Burmese President Thein Sein will come to London in the coming months for talks with Mr. Cameron.

On Wednesday, Aung San Suu Kyi was awarded an honorary doctorate from Oxford University, where she studied and lived with her family for years before returning to Burma in 1988.

She said in her acceptance speech that Oxford “stood up and spoke for her” during her long years of isolation under house arrest, saying she survived the imprisonment partly because of what she learned at the university.

Aung San Suu Kyi also said Mr. Thein Sein should not view the warm welcome she has received during her 17-day tour of Europe as a challenge.

In a television interview, the democracy leader said the reception is a sign of “how much the world wants Burma to change in the right direction.” She also said she does not view her new position as a perilous one.

“I think of it as a challenge. It's a challenge not just to me and my party but it's a challenge to the government as well, and of course to the people in general, because they must play their part.”

A nominally civilian government came to power last year, as the country's long-ruling military junta stepped aside. Aung San Suu Kyi — released from house arrest in November 2010 — won a parliament seat in an April elections.

Her tour of Europe has also included visits to Switzerland, Ireland and Norway, where she received the 1991 Nobel Peace Prize denied her while under house arrest.

Aung San Suu Kyi acts from Parliament address

“So many people in Burma gave up so much, gave up everything in Burma's ongoing struggle for democracy. And we are only now just beginning to see the fruits of our struggle.”

Act 2

” Our new legislative processes, which undoubtedly are an improvement on what went before, are not as transparent as they might be. I would like to us learn from established examples of parliamentary democracies elsewhere so that we might deepen our own democratic standards over time. ”

Act 3

“…That if we do not regard the rights we have, we run the risk of seeing those rights erode away.”

Act 4

“Now once again we have an opportunity to re-establish true democracy in Burma. It is an opportunity for which we have waited many decades. If we do not use this opportunity, if we do not get things right this time around, it may be several decades more before a similar opportunity arises again.”

Act 5

“The reforms taking place, led by President Thein Sein are to welcomed, but this cannot be a personality based process. Without strong institutions, this process will not be sustainable. “
