LONDON — IRA commander-turned-political peacemaker Martin McGuinness said Thursday that he regrets "every single life" lost in Northern Ireland's decades of violence and expressed hope that his handshake with Queen Elizabeth II would be a key building block in a new relationship between Britain and Ireland.
McGuinness, who is the deputy leader of Northern Ireland's Catholic-Protestant power-sharing administration, said his historic meeting Wednesday with the British monarch was meant to offer "the hand of friendship" to Protestants who were once his enemies.
"It was a meeting which, although short in length, can I believe have much longer effects on defining a new relationship between Britain and Ireland and between the Irish people themselves," McGuinness said in a speech to supporters at the Houses of Parliament in London.
McGuinness is an elected British lawmaker, but like other members of his Irish nationalist Sinn Fein party refuses to take his seat in the House of Commons. McGuiness said he would quit as a member of Parliament to focus on his duties in Northern Ireland, though he did not say when he planned to leave.
In an otherwise upbeat speech, McGuinness accused the British government of hampering further reconciliation in Northern Ireland with "wrong and unhelpful" decisions. He said Britain had failed to "acknowledge its role as a combatant in the conflict" that killed about 3,700 people over the past four decades.
The Provisional Irish Republican Army, which McGuinness once led, was responsible for some 1,775 of those deaths; British soldiers killed 309 people.
McGuinness accused Prime Minister David Cameron of a "lack of engagement," saying he and Northern Ireland's Protestant First Minister, Peter Robinson, had met U.S. President Barack Obama more times than they had met Cameron.
He slammed Cameron for failing to tackle issues that anger Irish nationalists, for example refusing to hold public inquiries into controversial killings of Irish republicans.
McGuiness encouraged Northern Ireland's British Protestant majority to respond to his royal handshake with compromise of its own.Comment on this story
In particular, he urged the Orange Order, a Protestant brotherhood, to end its policy of refusing to talk to Sinn Fein and to steer clear of flashpoint Catholic areas during its annual "marching season." The summer parades, a yearly show of communal strength, frequently bring riots in hardline Irish nationalist areas.
The overall tone of the speech was conciliatory, as McGuiness said decades of violence had been replaced by "compromise, agreement and peace."
"I genuinely regret every single life that was lost during that conflict," McGuinness said, promising "to work with others to find a way to deal with our past so that we can complete our journey to true reconciliation."
