Their romance has spanned four decades. They've had five weddings, two affairs, two divorces, dozens of lovers and four children between them. But something keeps bringing Coronation Street's favourite couple back together.

Now Ken and Deirdre are set to tie the knot for the second time – 24 years after they first said: ""I do"" – in a ceremony that is set to be the wedding of the year – possibly overtaking the Royal nuptials of Charles and Camilla, whose ceremony is on the same day.

ITV1's When Ken Met Deirdre captures actors Anne Kirkbride and Bill Roache as they prepare to take their characters down the aisle again.

The pair reveal what they really think of Ken and Deirdre's relationship – and what it has been like working so intimately together over the years.

The programme takes a look back at the clinches, romance, rows, tears and heartbreak Ken and Deirdre have experienced.
