Pierce Morgan's CNN show to end in March

It is the end of the road for Piers Morgan's prime-time talk show on US TV network CNN.

The former editor of The Daily Mirror told The New York Times it had been "a painful period" for the show, which suffered rather lacklustre ratings, BBC reported.

According to Morgan, the network's audience had wearied of a Briton's take on American cultural issues.

He said he was in discussions with CNN about a new role at the channel after the end of the show, probably in March.

The 48-year-old came in as a replacement for Larry King three years ago and interviewed statesmen and celebrities, including ex-president Bill Clinton, and financier Warren Buffett, with Oprah Winfrey his first guest.

However, in recent months, what had garnered the most attention was his outspoken remarks about gun ownership.

He told the New York Times  that he was a British citizen, debating American cultural issues, including guns, which had been very polarising, and there was no doubt that there were many in the audience who were tired of him banging on about it.

Morgan, 48, had been privately telling friends for a while that he experienced periods when he had been energised doing the show, called Piers Morgan Live, The Independent reported. However, mostly during long periods when there was not much happening on the US news front, he felt he had guests who bored him and the viewers too.

Morgan's problems affected his rating, which regularly came in much behind Fox News Channel, owned by Rupert Murdoch, and the other main rival MSNBC.

Morgan's troubles don't end with his unimpressive stint at CNN. Earlier this month he admitted to having wilfully submitted to questioning by police in London in December in connection to the ongoing phone hacking investigation during his time at the Mirror, where he was editor-in-chief from 1995 to 2004.
