In Northern Ireland, from the late 70s to the early 90s, the IRA killed over 40 alleged informers.

But the man who often found, tortured and sometimes killed these people on behalf of the IRA

was himself an informer, a secret British army agent with the codename Stakeknife.

Who gets to play God? And why me? Why my family? When lies are still being told to this day,

who do you believe? I wouldn't even know where to start and I'm with the IRA.

Steakknife. Listen first on BBC Sounds. BBC Sounds, music, radio, podcasts.

Many thanks. good afternoon.

The urgent topic of climate change is front of mind for millions of people.

The Extinction Rebellion protests continue.

David Attenborough has a new BBC documentary on climate change,

and the number of people searching Google for the word environment has trebled since December.

Clearly, many feel that something has to be done, but what that something is may be harder to

answer, perhaps using more public transport, walking or ditching plastic bags, for instance.

But one of the most direct ways we might make a difference is to change our energy supplier to a less environmentally damaging option.

Like these climate change protesters who spoke to us in central London today.

In my home, we only use electrical power. We don't use any gas or non-renewables.

I use 100% wind farm.

Right now our energy supplier is 100% renewable.

In the home we've got a our energy supplier is 100% renewable.

In the home, we've got insulation and double glazing,

save some money, pure drafts, warm and cosier home.

Some nice tips with some good music there.
