George W Bush, who was the 43rd president, issued a statement following his father's death.
"Jeb, Neil, Marvin, Doro and I are saddened to announce that after 94 remarkable years, our dear dad has died", he said.

The decorated war pilot and former Central Intelligence Agency chief suffered the ignominy of being a one-term president, denied a second term over a weak economy when he lost the 1992 election to upstart Democrat Bill Clinton. In 1945 he had married Barbara Pierce and the couple went on to have six children, though their daughter, Robin, died in 1953 of leukemia when she was four years old.
It was there that Bush became involved in politics, first losing a U.S. Senate race in 1964 before winning election to the U.S. House of Representatives in 1966.
Remarkably, Bush developed a late passion for skydiving, jumping to celebrate his 85th birthday in 2009 and the opening of his presidential library in 2007.

The elder Mr Bush, the son of a senator, rose through the political ranks: from congressman to United Nations ambassador, Republican Party chairman to envoy to China, CIA director to two-term vice president under the hugely popular Ronald Reagan. He carried 40 states and achieved a almost 7 million-vote plurality, becoming the first sitting vice president to be elected president since Martin Van Buren in 1836.

A spokesman for George Snr said he apologised for any offence caused and that any inappropriate touching was "unintentional".
