As the most evil race in the galaxy, it was refreshing to see a change of heart for a Dalek who glided down the aisle as a ring bearer at a Gravesend wedding.

After 30 years of happy marriage, Paul, 55, and Joanne Seymour, 52, decided to renew their vows at St Peter and St Paul’s Church in Milton Road on Saturday.

But as a surprise to their 80 guests, the pair walked down the aisle to the Doctor Who theme tune - and when the ring went ‘missing’, it was up to the planet Skaro’s most fearsome inhabitant to save the day.

Paul, of Sandcliff Road, Erith, dressed in long scarf, question mark pullover, fez and carrying a Sonic Screwdriver had a brainwave by deciding to raise money for the Little Buds Fund for special care babies at Darent Valley Hospital.

He said: “We didn’t really plan to do all of this.

“Originally we just wanted to walk down to aisle to the Doctor Who theme tune but then when Jo bought me the Dalek for my birthday, well, this all happened.

"It’s definitely something to remember.

“The vicar was a bit sceptical about it, particularly the Dalek as it’s the epitome of evil but thankfully that all worked out.

“When we spoke about doing it for charity, he was up for it and even let us split the collection plate from the ceremony.”

The pair originally met on a blind date when Joanne was a trainee midwife and Paul was an undertaker.

Paul’s brother Martin was meant to hand over the ring following a rousing rendition of I Vow to Thee, My County, but said he had lost it.

He darted out of the church before returning a few minutes later claiming the minibus driver was bringing it in.

As smoke began to pour in from the main doors, they flung open and a Dalek, wearing a bow tie, came down the aisle with the ring on its sucker - much to the surprise of the guests

The ring was special ring for Joanne, made from her original wedding ring and from Paul’s parents' rings.

Rector at the church Graham Herbert was also in on the act, welcoming the Dalek to Earth before it ordered the congregation to ‘all show respect to the reverend’.

Having got the ring, and bending down on one knee, Paul said: “You look just as beautiful today as you did when I first met you and I wanted to ask you just one more time, will you marry me?”

Joanne, who took part in the Olympics opening ceremony in 2012 during the NHS section, said yes and Revered Herbert ended the wedding with ‘you may kiss - else you be exterminated’.

Mr Herbert said: “They’re great science fiction fans and that love of sci-fi is part of their marriage.

“They wanted to raise funds for the Little Buds fund at Darent Valley Hospital where they both work and they’re a lovely couple and are always willing to do something for someone else and so I was happy to do something for them.

“I’ve never had a wedding quite like this.”

Paul, who plays Father Christmas at Darent Valley Hospital every year, works in the maternity ward while Jo is a midwife.

The pair also received a special signed photograph from David Tennant (Doctor number 10) congratulating them on their special day.

A spokesman for Darent Valley Hospital said: “We wish Joanne and Paul the very best of health and happiness as they continue their adventures in space and time together.

“Reaffirming their vows in front of their family, friends and at the point of a Dalek blaster was a delight to see and hear.

“Paul made a wonderful Doctor Who at his wedding but there was no mistaking who is the Master. May they enjoy their travels in Scotland this week and be back before they left.”

The couple had a party following the ceremony at Nurstead Court in Meopham with TARDIS table decorations, Daleks and Cybermen.

The pair are now planning to hold a charity auction of Doctor Who memorabilia and potentially hold a sci-fi event in Gravesend to raise more money for the Little Buds fund.
