In an interview with Jewish website Tablet, conducted by Israeli historian Benny Morris, Peres says: "There are several million Muslim voters [in the UK]. And for many members of parliament, that's the difference between getting elected and not getting elected".
On Labour politicians, he said: "They think the Palestinians are the underdog. In their eyes, the Arabs are the underdog. Even though this is irrational".
He offers the illustration of Israeli disengagement of Gaza as evidence of bias. "We evacuated 8,000 settlers, and it was very difficult … It cost us $2.5bn in compensation.
"We left the Gaza Strip completely. Why did they fire rockets at us? For years they fired rockets at us … When they fired at us, the British didn't say a word".
Peres's remarks chime with a deepening concern among Israeli politicians that opinion, particularly in Europe, is turning against the Jewish state.
Last week, David Cameron described Gaza as a "prison camp" during a visit to Turkey, which some commentators interpreted as a hardening of an anti-Israel position in Britain.
Peres, 86, also claimed there is more antisemitism in the UK than is acknowledged. "There is in England a saying that an antisemite is someone who hates the Jews more than is necessary".
He added: "There has always been something deeply pro-Arab, of course, not among all Englishmen, and anti-Israeli, in the establishment".
He cited historical examples of Britain's failure to support Israeli interests, including abstention in the 1947 UN partition resolution, an arms embargo against Israel in the 1950s and a defence treaty with Jordan. "They always worked against us," he said.
However, he conceded that there is support for Israel today on the British right.
Yesterday Labour MP Denis MacShane, who chaired a parliamentary inquiry into antisemitism in 2005, said Peres was wrong.
