LABOUR leader Jeremy Corbyn was last night urged to axe the convicted fire-raiser Lord Mike Watson from his front bench.

The disgraced Scots peer, who served eight months in jail after drunkenly starting a fire in a crowded hotel, was named on Friday as Corbyn’s education spokesman in the Lords.

The appointment was particularly awkward for Scottish Labour leader Kezia Dugdale, as she has made education her key policy area at Holyrood.

Corbyn’s spokesman said Watson, 66, deserved a second chance: “He has spent his penalty and we are in favour of rehabilitation."

However SNP deputy leader Stewart Hosie said the promotion was plain wrong.

“Jeremy Corbyn needs to reconsider this and do the right thing by removing Lord Watson from his front bench team. We know many people in Labour are refusing to work with the new leader - but appointing a peer who was found guilty of fire-raising, endangering people's lives, is a step too far.”

A former tourism minister and MSP for Glasgow Cathcart, Watson was caught on CCTV setting fire to curtains at a political awards ceremony in Edinburgh in November 2004.

He eventually plead guilty to wilful fire-raising.

Passing sentence in September 2005, Sheriff Kathrine Mackie revealed a social enquiry assessment had concluded there was a “significant risk” of him re-offending.

She said: “Fire-raising is a most serious crime. The potential for serious injury to guests and staff within the hotel, and for very significant damage to the property, was considerable."

Watson was sentenced to 16 months in prison but released after just eight.

Despite calls for him to be stripped of his title, he resumed his seat in the Lords.

Expelled from Labour for his crime, he was allowed back into the party in 2012.
