Sonia Fowler, lesbian nurse and estranged wife of Martin may be killed off in the hit soap EastEnders.

The rumours of the dramatic storyline comes after Natalie Cassidy who plays Sonia and James Alexandrou who plays Martin both announced their decision to leave the long running drama.

The Daily Star claims that Martin will either face life in jail or commit suicide after he kills his estranged wife.

“There’s a feeling that neither Natalie nor James will want to come back once they have left, ” a source told the newspaper last night. “We are therefore preparing a series of blockbusting alternatives for their departure and the strongest one so far is Sonia’s murder.

“Martin’s been left humiliated and heartbroken by his marriage bust-up. A crime of passion is a logical progression.”

The story line is understood to revolve around the future of the couple’s child Rebecca who comes to live in Walford. Martin becomes enraged that Sonia intends to bring up their daughter in a lesbian household and kills her during an argument.

Casidy who has played Sonia Fowler for thirteen years first arrived on Albert Square as a cheeky, trumpet playing girl.

The following years saw her give birth without knowing that she was pregnant, her mother Carol abandoning her, kidnap her adopted child, become engaged to car mechanic Jamie Mitchell, nursing him to death after he was run over by Martin Fowler, the father of the child she gave up for adoption.

In recent years she married her fiancée’s killer, enrolled on a nursing course, dealt with her husband’s psycho stalker and the death of her child’s adoptive parents in a car crash. Most recently, she has begun a lesbian affair with fellow nursing student Naomi.
