OTTAWA - An NDP MP who stood by an aboriginal chief as she began a hunger strike earlier this month says the situation is now becoming deadly serious.

Charlie Angus says he will be visiting Attawapiskat Chief Theresa Spence on Friday to check on her health.

Angus helped catapult the grave situation on Spence's reserve into the international spotlight last year but said he was concerned about her taking on the hunger strike.

She began the fast on Dec. 11 and has said she'll continue it until she receives a meeting with the prime minister and governor-general to discuss the First Nations relationship with the Crown.

Aboriginal Affairs Minister John Duncan has repeatedly offered to talk to Spence but has been rebuffed.

Angus says the only resolution in his mind is for the prime minister to show leadership and agree to meet.
