THE mother and step-father of Olivia Campbell-Hardy are tying the knot this weekend.

Charlotte Campbell and Paul Hodgson are marrying on Saturday in Bury, fulfilling one of Olivia's dearest wishes.

The pair will marry at Bury Registry Office on Saturday before going to a small family and friends reception.

Ms Campbell, said: "We have a lot of mixed emotions ahead of this weekend.

"We're happy we're finally doing it but obviously the main guest can't be there."

Olivia Campbell-Hardy, was 15 when she was killed by the suicide bomber at the Manchester Arena in May.

Ms Campbell has said Olivia always wanted her mum and step-dad to marry and had planned the day down to the last detail.

On Saturday, the bridesmaids will be in blue said Ms Campbell, keeping to Olivia's plan and a recording of Olivia singing the John Legend hit 'All Of Me' will be played.

Ms Campbell said: "Olivia always planned to do a song for us at the wedding but we don't know what it would have been, but 'All Of Me' has become really special."

In the aftermath of the attack, footage of Olivia singing the hit at her grandparents' wedding was shared online, showing off the keen singer's talent.

Ms Campbell and Mr Hodgson appeared on Good Morning Britain yesterday morning, six months on from the arena attack.

Ms Campbell explained this Saturday is the nearest to Olivia's birthday. She would have been 16 on Tuesday.
