The speaker of Britain's House of Commons says a pie attack on media mogul Rupert Murdoch at a parliamentary committee hearing could lead to permanent security changes.
An activist launched a shaving foam pie at Murdoch, 80, inside the Houses of Parliament in July as Murdoch testified about Britain's tabloid phone hacking scandal.
Speaker John Bercow said Monday the incident had exposed inadequate security arrangements.
Visitors in the future may face new restrictions during high profile events, including restrictions on the type of items they can bring into Parliament. Bercow said officials will also consider creating a new post of director of security.
Jonathan May-Bowles pleaded guilty to assaulting Murdoch and was sentenced to six weeks in jail.
