Sophie ThompsonSophie ThompsonIt's important for the EastEnders Mitchells to have a trusted lawyer on hand.

And since their long-standing brief Marcus Christie did a flit there has been a vacancy.

Actress Sophie Thompson - sister of Brit favourite Emma Thompson - will be finding her niche in Albert Square when Phil employs her to do some conveyancing work.

Yep, that's right - not to get him out of bother, just a straightforward bit of legal assistance, all above board. Who'd have thought it?

You'll recognise Stella from Four Weddings And A Funeral. She played lusty bride number two, Lydia, and she also appeared as reliable servant Dorothy in Gosford Park.

Sophie, 44, will be joining the EastEnders cast in autumn to play Stella Crawford but don't expect her to be a one-sided legal eagle.

An insider told the Daily Mirror: "Stella used to be a high-flyer in the City but it all went wrong as her marriage collapsed.

"Now she is trying to rebuild her life by working in a small firm. She's got secrets to hide."
