Simon Wright, 30, from Brighton, and Alan Jamieson, 41, from Manchester, stood on opposite sides of the net on Centre Court and tried to play tennis.

One managed to serve a tennis ball towards the Royal Box before they were ushered off the court by security men.

The men, who said they belonged to Real Fathers 4 Justice, were arrested.

Both wore T-shirts with a version of the Wimbledon logo with "Family Law It's a Racket" emblazoned across it.

Before being led away, Mr Wright said: "There have been 20 family law court cases and still I don't get to see my child and this is what I have had to resort to."

Mr Jamieson added that he was not able to see his children either.
