This is the Guardian.

Today, a five-day boat journey to the Chegos Islands

and a 50-year struggle for justice for the people of Britain's last colony in Africa.

Hello. Hi, there. It's Philippe Sanser with Bruno. Hello, Philippe. How are you?

Very well. I'm with Bruno and his bathroom, which we're using as a studio.

The line is good, given everything, given bathroom on a boat in the Indian Ocean.

It's pretty good. No, no, you just cut out.

Philippe Sanser is an author and international lawyer.

Last week, he left the seashells, a country off the coast of East Africa, a border yacht,

carrying scientists, journalists and five Chegos Islanders, making an unauthorized trip home.

Let's turn to Mauritius, the government there, is sending a boat to the dispute Chegos Islands

in the Indian Ocean, another boat which is to conduct scientific research.

We spoke to Philippe with a little help from Guardian Video journalist Bruno Rindvalucri,

while they were still in the way. With two days out of seashells, we're exactly halfway.

It's a thousand miles. The way has been mixed a few hours, pretty choppy, then calm,

and we expect to arrive, make land in two days' time.

Olivier Bencou was from Perus Banius, one of the islands that makes up the Chegos archipelago.

On the boat, we are all excited to see our birthplace. By tomorrow,

midday, we will be able to see Perus Banius, one of the main islands where I, my son, was born.

For the Mauritian government, whose case Philippe is pursuing, it's an opportunity to stake its

claim to islands it says was stolen from it by the British government decades ago.

For Olivier and the other Chegosians, it's a chance to see home again.
