A Southgate man jailed for life last year for his involvement in a suicide-bomb plot in London has had an attempt to appeal against his conviction rejected.

Yassin Omar, 27, of Curtis House, Ladderswood Way, was given a 40-year jail term last July.

He had planned to blow himself up on a train at Warren Street Tube station on July 21, 2005, as part of a co-ordinated attack by a gang of four Islamic terrorists.

His council flat was used by co-conspirator Muktar Ibrahim to mastermind the attacks, which were intended to exceed the July 7 atrocity, which killed 52 people and injured more than 1,000 others.

Omar, Ibrahim, Ramzi Mohammed and Hussain Osman all applied for permission to appeal against their convictions last month.

Their applications were rejected by Court of Appeal judges Sir Igor Judge, Mr Justice Forbes and Mr Justice Mackay yesterday.

Sir Igor said: "On 21 July, 2005, London came within a short breath of wholesale murder by terrorists.

"The explanation why the date will not be twinned in the annals of its venerable history with the murderous outrage perpetrated on 7 July, 2005, is simple: it was sheer good fortune.

"These were merciless and extreme crimes.

"As they were rightly meant to be, the sentences were severe and extreme. Beyond doubt, however, they were utterly justified."
