The year 2016 promises to bring about the biggest upheaval in British politics for a generation. In 12 months from now, the political landscape may be unrecognisable.
It is not that there will be a general election to alter the political complexion of the United Kingdom.
It is that the two major parties – Labour and Conservative – are both embroiled in internal turbulence of such ferocity that they could lead to resignations, even splits, which would dramatically transform the line-up of the House of Commons.
In the case of Labour, it all rests on the left-wing leader Jeremy Corbyn. Although he won the party leadership contest with a huge majority, he still remains hugely unpopular among substantial swathes of the Parliamentary Labour Party who would like to get rid of him. And the likelihood of that happening must vary between remote and zero. The Labour leadership election procedure allows too much weight, some would say, to outsiders. Hence why many Labour MPs are saddled with a leader they do not want.
But Corbyn shows no signs of surrendering. As such, there remains a real prospect those frustrated Labour MPs, who cannot bear to have Corbyn as their leader, could form a breakaway movement, like that of the SDP. Who could lead such a rebel group? It is impossible to say. Those who are looking for a change would like Hilary Benn, whose speech on bombing Syria made an impact, to march alongside them. But I think that is unlikely to happen.
The trouble in the Conservative Party is of a different nature. It is all to do with David Cameron’s negotiations with Brussels grandees to get a better deal for the UK within the EU – or quitting altogether.
Many Tories who are anxious to leave the EU are suspicious of Cameron’s motives. They suspect his basic instinct is to remain a member.
The idea (still unresolved at the time of writing) that fiercely Eurosceptic Cabinet Ministers would be banned from campaigning against the Government line ahead of the referendum, is preposterous.
Tories are noted for their loyalty, but there comes a point when that loyalty may be taken for granted.
The Prime Minister is on a tight-rope at the moment, and it may result in a nasty fall.
