Marcus and Maria's relationship is set to hit the rocks when Todd Grimshaw makes his return to Corrie's cobbles this autumn.

Todd is set to rock up on the street in the next couple of months, and his arrival won’t go unnoticed by certain Weatherfield residents, especially Marcus Dent.

Marcus, who is currently dating hairdresser Maria Connor and was previously in a long-term relationship with Sean Tully, is set to have his head turned by Eileen’s youngest son Todd.

Soap bosses are hoping Todd’s efforts at trying to steal Marcus away from Maria will have viewers on the edge of their seats.

A show insider told the The Mirror: “Coronation Street has never shied away from controversial issues and this will be one of the most talked about ever".

“Producers are delighted to have Todd’s character back and he will be thrown straight into the centre of a big story.”

Todd was last seen on the Street for a brief appearance in April 2011, but is set for a much longer stay this time round.

Charlie Condou, who plays Marcu,s has previously hinted that there might be trouble in store for Marcus and Maria. He said:: “At the moment, Maria and I are still very much together.

"I don’t see an end to it at the moment, but there are definitely going to be big dramas ahead, and they’re all going to be because of this issue – the fact that Marcus is a gay man. I think this is going to keep rearing its head.”
