Cilla Black's post-mortem results 'inconclusive'

The post-mortem on Cilla Black has not revealed why she died, reports say.
Quoting sources from the Spanish police, the reports maintain her death was not suspicious, but that the post-mortem results are âinconclusiveâ.
Earlier in the day, it was suggested Spanish police were investigating whether her death was caused by a fall from a dizzy spell, caused by a sudden temperature change in the room.
Black may have walked from an air-conditioned room in to midday heat, with the change in temperature causing her to become dizzy, The Sun newspaper reported.
Ahead of the post-mortem examination, police in Spain said âeverything at this stage is pointing towards her death being the result of natural causesâ.
Her sudden death at her home in the south of Spain has left friends, family and the British public in shock.
Tributes have been pouring in for Black, 72, led by close friends such as Sir Cliff Richard, Sir Paul McCartney and Christopher Biggins.
She rose to fame in the 1960s as an associate of The Beatles and their manager Brian Epstein.
Born Priscilla Maria Veronica White in Liverpool, she became the first woman to have her own prime-time chat show on BBC One.
Her star continued to shine brightly, and she had two number ones in 1964 - Anyone Who Had A Heart and Youâre My World.
In a touching tribute to her, Sir Cliff said he was due to visit her at her house in Spain next week.
âHer passing away is a particular shock because despite the aches and pains we all suffer, she was always so upbeat,â he wrote in The Sun.
Former Beatle Sir Paul McCartney paid tribute to her from Los Angeles, saying: âSuch a shock to hear about Cillaâs passing. She was a lovely girl who infected everyone with her great spirit.
âFrom first meeting her as a cloakroom girl at the Cavern in Liverpool, to seeing her many times since, she always had a fun-loving dignity that made her a great pleasure to be around.
âShe had a fine distinctive voice and was always a bit of a laugh. It was a privilege to know and love her.â
And former Beatles drummer Ringo Starr said: âI just heard the news Cilla Black has left us. She was a good friend, we will all miss her. Peace to Cilla, peace and love to the family, R&B.â
EastEnders star and her good friend, Barbara Windsor, described her death as âawfulâ.
She told the BBC: âI was only with her a couple of weeks ago. Iâve seen her twice in the last few weeks, and as always she looked immaculate. That was the thing about Cilla, she always looked spot-on. But I knew she wasnât very well, she didnât seem well.â
Windsor added: âI liked her, we got on well. She was nothing like me in personality at all, but she was a good, good all-round performer.â
