The Labour Party leadership contest turned into a tale of two lords a-leaping yesterday.

Lord Prescott deplored Tony Blair’s sneer that anyone inclined by their heart to support Jeremy Corbyn should “get a transplant.” The former deputy prime minister pointed out that his ex-master’s war in Iraq — which they both supported — was a major reason why Labour lost the 2010 general election.

He could have added that there were other reasons too: notably the policies which enriched the wealthy and big business and enabled the Lib Dems to pose as a party of peace and social justice.

Lord Mandelson also leapt into the fray yesterday, blaming Ed Miliband for Labour’s failure to win this year’s election and leaving the party with a “terrible legacy.” Yet it was under the leadership of Blair, Mandelson, Prescott and Gordon Brown that Labour steadily lost five million votes between 1997 and 2010.

Under Miliband and his slight shimmy leftwards, Labour actually increased its share of the poll on May 7 and gained three-quarters of a million votes.

Under Jeremy Corbyn, Labour would not only have the right policies for the people of Britain, but also ones that could inspire millions of voters to return to Labour — and enthuse many of the 15 million electors who didn’t vote at all on May 7.

It speaks volumes about millionaire Tony Blair that he would rather Labour lose the 2020 election than win on such a left-wing manifesto.

Ever-helpful West won the war for Isis

Western skies continue to darken. Tuesday’s large demonstration in Kiev by Right Sector paramilitaries and their supporters signalled their intention to overthrow the right-wing regime they helped install in February 2014, cheered on by Western politicians, diplomats and media pundits.

A blind eye was turned to fascist involvement in the coup, and has been ever since to their murderous activities alongside regular troops in eastern Ukraine.

Now the fascists are on the march in the west, preparing for a coup against pro-Western stooge President Poroshenko.

One day before, Islamic State (Isis) terrorists murdered 32 young socialists in the Turkish town of Suruc on the border with Syria.

For three months, the Ankara government refused to allow Turkish, Syrian and Iraqi Kurds to cross the border and help break the Isis siege of Kobane. Turkey’s tacit support for fellow Islamists in their war against the Assad government in Syria drew little criticism and no condemnation from Nato and anti-Assad allies Britain and the US.

Now Isis is taking its bloody campaign into Turkey, threatening to destabilise a country which borders Greece, Bulgaria and the EU.

Of course, it was Western support for the mojahedin against the progressive pro-Soviet government of Afghanistan in the 1980s which first boosted jihadi fundamentalism. Western state terrorism in that country and Iraq, courtesy of Tony Blair and George W Bush, then won thousands of new recruits for Islamist terror groups.

Western policy is proving to be an unmitigated disaster everywhere. That’s another good reason for supporting Jeremy Corbyn, the only Labour leadership contender who dares to challenge it.
