A veteran Yorkshire peace campaigner says she was "amazed" how easy it was to climb the gates of Buckingham Palace to stage her protest against the visit of the US president.
The protest lasted nearly three hours
Lindis Percy, 61, from Hull scaled the 20 feet high gates at the front entrance to the palace at 1600 GMT on Monday.
President George Bush will be staying at Buckingham Palace during his state visit.
Wearing a yellow jacket she unfurled a US flag upside down on the gate. On it were the words "Bush not welcome".
After nearly three hours she came down and was arrested by waiting police officers on suspicion of causing criminal damage and breach of the peace.
Lindis Percy has been involved in protests since 1990
She was later bailed at Charing Cross police station.
Mrs Percy said she did not think she would be able to climb the gates so easily.
"There was not a policeman in sight along the gate so I just climbed the gate," she explained.
"My purpose was peaceful but the world is in such a state that anything could have happened.
"I was amazed at the ease of it."
A spokeswoman for Metropolitan Police said Mrs Percy did not manage to enter the protected area of Buckingham Palace.
Born in Leeds, Mrs Percy is a nurse, midwife and health visitor.
She has three grown up children and four grandchildren.
She was first arrested in 1990 shen she started work with the Otley Peace Action Group at US listening base at Menwith Hill near Harrogate.
Since then she has been in court on numerous occasions for trespass on Ministry of Defence property.
