article: For years it has been their ritual - women who lost children and husbands in 30 years of armed conflict between the Kurds and the Turkish state. I meet them in Diyarbakir - the final stop of our election trip across Turkey. Age and exhaustion are etched on their faces. One wears a necklace with a picture of her missing children. Another has a bracelet bearing the Kurdish flag. "Turkey doesn't think we Kurds are humans", says Sakine Arat, 80, who lost four sons and one daughter in the fighting. "We've tried all the political parties but none sided with us. Now we've found one - the HDP - that treats us as equals. So we will vote for it." The People's Democratic Party (HDP) is the one to watch in Turkey's election on Sunday. Its roots and support base are Kurdish but it has broadened out, becoming a powerful voice of the Turkish left. Its candidates used to run as independents, winning a handful of seats. But this time, the HDP is a single, united party - and polls show it could cross the 10% threshold to get into parliament, potentially gaining dozens of MPs and depriving Turkey's governing AKP of a majority. That would stop President Recep Tayyip Erdogan from changing the constitution to give himself more powers with an executive presidency - and is one reason why staunch Erdogan opponents are drawn to the HDP. "Turkish soldiers burnt my home four times," says Dilsah Ozgen, 76, who lost her husband and two sons. "I believe in our HDP. We will pass the 10% and drown Erdogan in a flood of votes," she says. There are around 15 million Kurds in Turkey - 20% of the population. For decades they were repressed, their identity denied: "There is no such thing as Kurds; they are simply mountain Turks," was the official refrain. In the 1980s, the Kurdistan Workers' Party (PKK) was formed, waging a three-decade insurgency against the Turkish state, some fighting for greater autonomy, others for independence. Forty-thousand people died. The group is still labelled a terrorist organisation by Turkey, the US and EU. Peace is fresh. Although conditions for Kurds have improved, the fragile ceasefire has been shaken by clashes as the peace process has stalled and the government has hardened its nationalist rhetoric. Many Kurds who supported the AKP have now shifted allegiance to the HDP. I join a local HDP candidate, Ziya Pir, at a Diyarbakir cultural centre. Around him, supporters play traditional instruments and perform songs in both Kurdish and Turkish, appropriately enough for a candidate who is not actually Kurdish. It epitomises the message of unity, of cultural crossover, that the HDP is trying to spread. "I'm Turkish - from the Black Sea - and initially people asked me: 'Why are you joining a Kurdish party?'" says Mr Pir. "But I told them it is not a Kurdish party; it is Turkish. We want a Turkey in which all people can find themselves". His uncle, Kemal, was a founder of the PKK. But he insists
