Economy, energy and care.

That will be the focus of Britain's newly-appointed Prime Minister Liz Truss, she said in her first speech.

In addition to promising investments in new hospitals, infrastructure and power generation, she made promises of major tax cuts.

But the most pressing issue for the prime minister is the skyrocketing energy prices in the country.

- This week I will take measures to manage electricity bills and secure our future energy supply, Truss said in the speech outside Downing Street.

She described the development in Great Britain and the rest of Europe as a "powerful storm".

- Together we can ride out the storm.

Praised Johnson

Her predecessor Boris Johnson was forced to resign after growing internal criticism of the many scandals he had been involved in. However, Truss spoke of Johnson in positive terms, praising him for his work on the mass vaccination against covid-19 and the handling of Russia's invasion of Ukraine.

- History will look at Boris Johnson as a hugely significant Prime Minister.
