Mercy Olubunmi is set to leave Albert Square later this year, EastEnders bosses have confirmed.
The student, played by actress Bunmi Mojekwu, is already battling to stay in Walford after the UK Border Agency threatened to deport when it emerged her visa expired.
Arthur 'Fatboy' Chubb, played by Ricky Norwood, has offered to try and save his friend from the immigration authorities by proposing to her, but an EastEnders spokesperson revealed Mercy will leave the soap in July.
They added: "Bunmi has done a great job of bringing the role of Mercy to life and we wish her every success in the future."
Mercy arrived in Albert Square in on internet spin-off EastEnders: E20 in January 2010.
She was initially the only character who did not move over to appear in the main show, but Bunmi began making regular appearances in EastEnders from May.
As Sam Attwater and Emer Kenny, who played Leon and Zsa Zsa have also left EastEnders, Ricky will be the only E20 cast member left in Walford.
