The cost-of-living crisis, punishing energy and mortgage bills, and the continued strain on public services in the wake of the pandemic have dominated domestic politics.

Rishi Sunak, the UK’s third prime minister in a year, tried to present himself as a new broom, but found himself dragged back into Tory infighting and sleaze.

One of his predecessors, Boris Johnson, quit as an MP after seeing the damning findings of a Commons report into his repeated lies to parliament over Covid rule-breaking.

Scottish politics also saw more than its fair share of drama, starting with Nicola Sturgeon’s resignation as First Minister in February after more than eight years in Bute House.

She had become too polarising a figure to change voters’ minds about independence or sell them on the merits of SNP policy, she admitted in an emotional farewell.

But it proved only the beginning of an extraordinary run of events for her party.

Her husband Peter Murrell quit as chief executive during the leadership contest after the party misled the media about losing almost a third of its members.

Kate Forbes, Humza Yousaf and Ash Regan attacked one another in a bruising fight for the top.

Holyrood, which had been expecting a relatively sleepy year without an election, was convulsed as never before.

There were also growing cross-border tensions between London and Edinburgh over Holyrood’s powers, with the sinking of the DRS recycling scheme and a looming court battle over Westminster’s block on the Gender Reform Recognition Bill.

Through it all has been the growing drumbeat of the general election, as Labour, the SNP and the Tories contemplate a pivotal encounter with the electorate.

While on the international front, the war in Ukraine has ground on remorselessly.

Started in 1999, the awards are the highlight of the Scottish political calendar, and are headlined by ScottishPower and sponsored by Aiir Networks and Drax.
