A memorial service has been held for Patsy Calton, the Cheadle Liberal Democrat MP who died from cancer weeks after defending her seat.
Lib Dem leader Charles Kennedy was among those attending
The service took place on Friday at St George's Church in Stockport.
Mrs Calton, 56, had held the UK's smallest majority before her win on 5 May. A date for the by-election has not yet been set.
Among those attending was the Liberal Democrat leader Charles Kennedy plus many of her constituents.
The Reverend Alan Bell praised her zest for life, commitment to public service and extraordinary courage when she was diagnosed with cancer.
Mrs Calton first won her seat in 2001 with a majority of just 33 votes from the Conservative Stephen Day.
Despite her health problems, she increased this to a majority of 4,000 in May, although she could not attend the count because she was undergoing treatment.
She was last seen at Westminster five days before her death, in a wheelchair after travelling by ambulance to swear her oath.
Before becoming an MP, she had served as a councillor for West Bramhall since 1994 and was chair of social services and deputy leader of Stockport council.
