"Having tried exceptionally hard to make our relationship work given the daily pressures surrounding us, it is with sadness that we have decided to go our separate ways.
"Our parting is amicable and both of us still care about each other very much but have found it increasingly difficult to maintain a normal relationship with constant intrusion into our private lives, and we have actively tried to protect the privacy of our child.
"Separation for any couple is difficult enough, but to have to go through this so publicly, especially with a small daughter, is immensely stressful.
"We hope, for the sake of our baby daughter, that we will be given some space and time to get through this difficult period."
