Who is Mo Harris in EastEnders and who is Fat Elvis?

Mo Harris in EastEnders is – despite her name – the head of the Slater clan. She is the scheming, entrepreneurial, kind-hearted matriarch with an eye for a deal and a very colorful love life with on / off partner Fat Elvis.

Mo is linked to the Slater brood by marriage. Their daughter Viv was Charlie Slater’s wife and the mother of sisters Lynne, Kat, Little Mo and Belinda.

Like the others, Stacey Slater calls Mo “Nan”, but actually she and Mo are not blood related. Stacey was Charlie’s great niece on the Slater side of the family.

Mo arrived in EastEnders in 2000 with the rest of the Slaters and stayed until 2016. She returned in 2018 but soon puts on her deck shoes and goes into the sunset with Fat Elvis, who has invited her on a cruise.

Although Mo didn’t hit the big screen in Walford until 2000, she grew up locally and had a lifelong rivalry with her former best friend, Pat Evans / Butcher. In fact, she even appeared on a spin-off show called EastEnders: Pat and Mo in 2004, telling the story of the two friends as young women.

Who plays Mo Harris in EastEnders?

Mo is played by Laila Morse. Her real name is Maureen Oldman – known as Mo – and she is the sister of actor Gary Oldman.

Laila didn’t start acting until she was 51 when she made her screen debut in Nil By Mouth – written and directed by Brother Gary. She played roles in The Bill and Great Expectations, among others, before being cast as Mo in EastEnders.

But Laila isn’t the only actress who plays Mo. Her Enders co-star Lorraine Stanley, who now plays Karen Taylor, took on the role for the 2004 spin-off EastEnders: Pat and Mo.

Mo and her seedy deals

When she got to Albert Square, Mo had nothing good to do. Soon she was selling stolen goods provided by her ex-boyfriend Fat Elvis and even starting a sex chatline. When Stacey married Bradley Branning, Mo tried to sell her wedding favors.

Mo has no shame. When Lucas Johnson was convicted of murder, she sold his Bibles as macabre souvenirs and kept a book that took bets on the identity of Archie Mitchell’s killer.

She requested benefits on behalf of Jean Slater, faked her own death and even stole the money Kat Slater left from her rape Uncle Harry.

Worst of all, Kat had twins when she was a teenager. She had thought she only had one baby – daughter Zoe – but was shocked to discover that she also had a son. And Mo had known everything. For a long time the discovery drove a wedge between Kat and Mo, but now the two have buried the hatchet.

Mo Harris in EastEnders and Fat Elvis

For years, EastEnders fans groped in the dark about Fat Elvis. We only knew what Mo had told us about him and the seedy goods he sent her – most recently a lot of one-eared chocolate bunnies the Slater kids got for Easter!

Mo and Fat Elvis were like lovers. They went to Spain together for a while and seemed made for each other – although he never showed up at Walford.

And then Mo amazed her family by announcing that she and Fat Elvis are connected!

He once appeared on screen, played by Shenton Dixon, when he and Mo were planning their wedding.

The happy couple went to new fields, but when Mo came back she came alone – Fat Elvis had left them because of his probation officer. What a rat!

Fortunately, the two have made up in the meantime and now he has persuaded Mo to leave Albert Square again to go into the sunset with him.

Will Mo ever return?
