Labour's deputy leader Tom Watson has reacted to May becoming Britain's prime minister.

"I congratulate Theresa May on becoming Prime Minister. To serve our country in this role is a privilege and an honour," he said in a statement.

"These are challenging times for Britain. The decision to leave the European Union has created enormous economic uncertainty and insecurity. The priority for the new Prime Minister must be to ensure the country is best placed to deal with the challenges ahead.

"We've today had warm words from our new Prime Minister about the need to stand up for more than a 'privileged few'. The sentiments are good ones but just like her predecessor the rhetoric is much better than the reality. The truth is Theresa May has been at the heart of the Tory Government for the last six years and is tied to its record. It's a record of failing to stand up to for working people and backing policies that are putting vital public services like the NHS at risk.

"The Labour Party will continue to hold this failing Government to account and push for a fairer alternative – that is what the country deserves."
