Just at update - the Barclay Brothers have recently attacked Private Eye over a spoof:
"The item, in Eye 1264, was a mock Telegraph front page (“Expenses Scandal Day 94”) exposing two tax-dodging brothers living on “the remote Channel Island of Brilleau” who pay a team of hacks to pontificate on MPs’ tax avoidance and other financial wheezes, and who acquired the newspaper from a convicted fraudster."
They also stopped the Sark postmistress from posting a copy of said page on the wall in the Post Office by threat of legal action.
Basically, they appear (from my point of view) to be acting like very insecure children who have never really grown up, and have the money to get their own way (by bullying anyone who criticises them) most of the time.
What they'll make of the band which calls itself "The Reclusive Barclay Brothers", goodness only knows!
