You couldn't make it up - exterminator in Downing Street

The pied piper of Downing Street: Ratcatcher called in to rid No.10 of vermin who made it on to News At Ten

Thus the Daily Mail headline. How many of the sub-humans inhabiting that street do you think will survive?

P.S. It just keeps getting better. Thus the Washington Post:

Rats are a common nuisance in London, where rubbish scattered on sidewalks provides a constant supply of food. Britain's National Pest Technicians Association said callouts of specialists to deal with unwanted rats in the capital were up 40 percent. Last year, performers in the city's entertainment district complained that vermin were frequently spotted back stage at theaters.
