Posh art critic Brian Sewell has slammed the level of intelligence displayed by the so-called prodigies in the Big Brother: Celebrity Hijack house.

Sewell said the programme was sold to him as housing the 12 brightest and best young Britons in their fields. Having watched the first show, however, he was very disappointed with the general intellectual level.

“As the programme wore on I began to dislike you more and more,” he said.

But then the latest celebrity hijacker gave them an opportunity to redeem themselves – setting them the task of creating a four-course dinner.
