OTTAWA -- The Harper government says Sri Lanka's Tamil minority continues to be fearful of the country's leadership, as a controversial Commonwealth summit wrapped there Sunday.

That's the conclusion of Deepak Obhrai, a parliamentary secretary to the foreign affairs minister, who travelled this week to Sri Lanka's Tamil region.

Obhrai was sent after Prime Minister Stephen Harper decided to boycott the Commonwealth leaders' summit over Sri Lanka's human rights record.

The country's government won't allow an independent investigation into the atrocities committed in May 2009 at the end of its 27-year civil war.

Obhrai says he was sent to Sri Lanka to keep the country's human rights record front and centre, which involved laying a wreath for all of its innocent civilian victims in the mainly Tamil north.

Obhrai says the government continues to question whether the 54-member Commonwealth, an association of former British colonies, is living up to its core values.

The leaders of India and Mauritius also boycotted the summit over Sri Lanka's human rights record.
