VERA Duckworth is to be killed off from Coronation Street in a heartbreaking storyline leaving husband Jack a widower.

One of British television's most enduring characters is being written out as actress Liz Dawn battles emphysema. Her departure will be screened in a special episode early next year.

Insiders say the scenes will be full of the show's characteristic humour.

Bill Tarmey, who plays Vera's roguish husband Jack, has signed a new contract committing him to the show until September 2008. Viewers will watch him adjust to life without his `little swampduck'.

Show bosses are closely guarding the details of Vera's exit. They have written three storylines and will decide which to use at the last-minute.

Liz says she is looking forward to retiring.

"It is going to be very emotional filming Vera's death scenes but I do think it is the right decision for the character," she said. "I have had 33 marvellous years in Coronation Street and will miss everyone very much."
