It is supposed to be a well-earned break from the stresses of high office.

But new prime minister Theresa May looked grim-faced as she was pictured taking a summer holiday walking in the mountains.

Downing Street had confirmed last week that May would be heading to Switzerland for a fortnight's break together with her husband Philip.

It's a far cry from the spots chosen by her predecessor David Cameron who preferred relaxing on the beaches of Cornwall and Lanzerote.

Instead, the new leader has more in common with German Chancellor Angela Merkel who is also spending the summer hiking in the mountains.

May is known to be a fan of active holidays and has written of her love of walking in an article for the Telegraph in 2007.

She and her husband had "discovered the joys" of walking in the country "quite by chance", she wrote.

It's a hobby she shares with Ms Merkel. When she visited Germany to discuss Brexit negotiations she gave the Chancellor two walking books as a 62nd birthday gift.

Switzerland is also an interesting choice for politics watchers looking for symbolism in the wake of the UK's vote for Brexit.

The state is politically neutral and is not a member of the EU.

A spokesman for Downing Street refused to give any details of May's planned holiday agenda.

She is due back into the UK on the 24th of August.
