The new BBC channel for Scotland has been broadly welcomed by politicians, led by First Minister Nicola Sturgeon who said there was "lots to welcome" in the announcement.

She added that that the commitment to invest and 80 jobs for journalists were "long overdue and very positive" but also expressed disappointed that the long-mooted 'Scottish Six' idea had been rejected.

Fiona Hyslop, culture secretary, said the announcement was a "real shift in the right direction from the BBC and responds to calls we've made for some time for a new TV channel for Scotland."

She added: "The Scottish Broadcasting Commission estimated in 2009 that a similar channel would cost around £75 million a year - more than double the £30 million announced today.

"It's vital that the new BBC Scotland channel has complete commission and editorial independence, and is provided with the funding needed to match ambition."

Ms Hyslop said Scotland was not "on an equal footing" with other devolved nations.

"The new channel will increase the proportion of the licence fee raised in Scotland that is spent in Scotland in years to come, but sadly will still fall well short of the proportionate share being spent in Northern Ireland and Wales."

She added: "In the intervening 18 months before the new TV channel is established, the BBC must invest in quality news and affairs programming so that they deliver content that is relevant to the people of Scotland as we move through Brexit, the triggering of Article 50 and beyond."

The Scottish Conservative shadow culture secretary Jackson Carlaw said it was an "extremely welcome announcement." Carlaw said.

"It's good for jobs, journalism, scrutiny and programming," he added.

Scottish Labour's culture spokesman Lewis Macdonald said the BBC had "listened to the views of Scots".

"A dedicated Scottish news programme in particular will be a great addition to our valued public service broadcasting," he said.

"This is a significant investment from the BBC and the hiring of 80 new journalists will be a boost to an industry that has sadly suffered in recent years."

Scottish Liberal Democrat culture spokeswoman Eileen McCartin said it was an opportunity to "scrutinise and celebrate events in Scotland like never before".

"However, this new service needs to be big enough to retain the best talent to make the best programmes for Scotland," she said.

Ross Greer, culture and media spokesman for the Greens said: "BBC UK management at long last appear to be listening to their Scottish audience and this turnaround in investment will be welcome after years of cutbacks.

"There are clearly exciting times ahead for the Scottish media industry and how we as a nation reflect ourselves, with the prospect of a Scottish Seven news programme from STV to be followed by a Scottish Nine from the BBC.

"I do wonder though, why this new news programme could not have aired on BBC One or Two, as the public clearly wanted. There is a risk of dilution rather than improvement here."
