On this week's Politics Show we play our own version of "spot the difference".
No, not two pictures of muddy footballers, one with his laces undone, the other with them done up - or one in short sleeved shirt, the other long.
Instead, my guests will be the contenders for the Liberal Democrat leadership, Nick Clegg and Chris Huhne.
And if you're wondering what I am talking about, consider this.
The two contenders went to the same school - Westminster - they're Oxbridge educated, and both cut their political teeth as MEPs in the European Parliament.
They have married successful, multi-lingual wives.
Both are, broadly, of the centre-right "Orange Book" tendency within the Lib Dems - and of course they both covet the same job.
This Sunday they will be live in the studio where we will seek to tease out the differences - but more importantly, consider what is at stake for the Liberal Democrats - and what difference it will make to you who leads Britain's third party.
If you have issues you'd like us to raise with either, or both of them, please let us know by filling in the form at the bottom of the page.
Keeping the lights on
Coal - a sunrise industry again?
Also Max Cotton reports on the battle for Kingsnorth power station.
Over the next few years a whole series of old coal fired power stations and nuclear power stations are to close down.
They've reached the end of their useful lives.
The Government will find it difficult to keep the lights on - literally - unless something replaces them.
Kingsnorth power station in Kent is the likely answer.
There is a planning application in to build a new coal fired power station.
It is hoped that it will burn cleaner and greener coal.
The trouble is that groups like Greenpeace don't think the technology is ready and that the Government has no chance of hitting its CO2 reduction targets if power stations like Kingsnorth get the go ahead.
Do join us this Sunday at noon.
