Former peer Nazir Ahmed has been found guilty of attempting to rape a young girl when he was a teenager in the 1970s.

Ahmed, 64, who was formerly Lord Ahmed of Rotherham, was found guilty on Wednesday of sexual offences against a boy and a girl dating back more than 40 years.

A woman told a jury at Sheffield Crown Court that Ahmed attempted to rape her in the early 1970s, when the defendant was about 16 or 17 years old but she was much younger.

The former politician was also found guilty of a serious sexual assault against a boy under 11, also in the early 1970s.

The jury was played a recording of a telephone call between the two complainants, made by the woman after she went to the police in 2016.

Tom Little QC, prosecuting, told the jury that the call was prompted by the man contacting the woman by email saying: “I have evidence against that paedophile.”

Ahmed, who denied all the charges, was found guilty on Wednesday of two counts of attempted rape and one of buggery.

The former Labour peer resigned from the House of Lords in November 2020 after reading the contents of a conduct committee report which found he sexually assaulted a vulnerable woman who sought his help.

The report made him the first peer to be recommended for expulsion but he resigned before this could be implemented.

Ahmed was charged along with his two older brothers, Mohammed Farouq, 71, and Mohammed Tariq, 65, but both these men were deemed unfit to stand trial.

Farouq and Tariq faced charges of indecent assault in relation to the same boy that Ahmed abused and, also on Wednesday, the jury found that they did the acts alleged.

The judge, Mr Justice Lavender, will determine on Wednesday afternoon when Ahmed will be sentenced.

The conviction of Ahmed follows a tortuous prosecution, which included the halting of a previous trial by a judge who bemoaned the antiquity of the allegations.

But Judge Jeremy Richardson QC said his decision to stop the original trial in March was due to failings in disclosing evidence which had “sabotaged” the proceedings rather than his misgiving over the length of time that had elapsed.

At a hearing earlier in the prosecution, Judge Richardson had noted that some of the then alleged incidents happened in the late 1960s when Harold Wilson was prime minister, Lyndon Johnson was the US president and the Vietnam War was raging.

In March the judge took the unusual step of ordering a permanent stay on proceedings, bringing the prosecution to a close.

But the Crown Prosecution Service (CPS) appealed against this decision and it was overturned by the Court of Appeal in June, paving the way for the new trial.
