The former It's A Knockout presenter had been convicted of carrying out an attack on the youngster by a jury at Preston Crown Court.

He was found guilty last week of assaulting her when she was under 16.

Hall, 84, had earlier pleaded guilty to another indecent assault on the same girl when she was 13.

That involved an incident at a dinner party where he crept into his victim's bedroom and assaulted her.

Passing sentence, Lord Justice Turner said of his offences: "It was an act of vile bravado and horrible betrayal."

The victim sat metres away and began wiping away tears with a handkerchief passed to her, as details of the offences were again mentioned in court.

Hall was sentenced to 12 months for the offence he admitted and was given an additional 18 months for the indecent assault of which he was convicted by the jury.

Last week, he was cleared of 15 counts of rape in relation to that woman and another who claimed they were sexually assaulted by him between 1976 and 1981.

The married father-of-two is currently in prison serving a 30-month term.

He had been jailed after he pleaded guilty last year to indecently assaulting 13 other young girls, aged between nine and 17, over a 20-year period.

The ex-BBC football match commentator had not been due for release from that custodial sentence until September.

Hall will not now be eligible for release until December 2015 as the latest sentence will only begin after the end of his current jail term.
