The Queen has been hit with another security scare after a male and female intruder scaled a fence and broke into her Windsor estate, reports claim.

The man, 31, and his girlfriend, 29, gained entry to the grounds of the Royal Lodge in Windsor Great Park last Sunday.

The lodge is Prince Andrew's official residence and he was at home at the time of the incident, insiders said.

The grounds are home to All Saints Chapel where the 95-year-old Queen - who is still grieving the loss of her husband Prince Philip last month - attends church.

It is also a spot where the Monarch rides her horses and takes her corgis for walks.

It comes just weeks after a 44-year-old woman who claimed to be engaged to the Duke of York was let into Royal Lodge by bungling security guards.
