The 35-year-old lost out to Siavash in the public vote.
Upon hearing the news, Marcus announced: "Thank fuck for that."
He hugged his fellow housemates goodbye and congratulated Siavash.
"No swearing," Lisa warned him as he left the house.
Marcus is the eleventh contestant with full housemate status to be evicted after Bea lost the public vote last week. Bea, Hira, Noirin, Karly, Kris, Sree, Angel, Sophia and Cairon were evicted in the preceding weeks, while Saffia, Kenneth, Tom and Isaac walked out. Beinazir was evicted after failing to gain housemate status.
