The early results suggested that the Conservatives had grabbed votes from both Labour and UKIP, signalling that May's bid to position her party in the political center ground and take a strong stance on Brexit may be paying dividends.
The main opposition Labour Party had won 609 seats, a net loss of 202, and controlled five councils, all in Wales.
John McDonnell said the party had to be more "effective" after it lost almost 400 council seats, won only two out of six of the new metro mayor posts and came third in Scotland, where it lost control of Glasgow council. That figure this time appears to be down to barely 3 per cent.
Everyone who backed Brexit a year ago must vote Tory on June 8 "if they believe in democracy", members of the latest HuffPost UK-Edelman focus group have declared. "The only party strong enough to lead this fight back is the Scottish Conservative Party".
The Labour leader promised that if he wins power on June 8, there will be "a reckoning" with big businesses and bankers who he accused of crashing the economy, stripping industrial assets and ripping off workers and consumers. Where the only variable to be determined is how big could the Tory majority be? The huge majority she covets will free her from worrying about how to sell the Brexit deal she gets to Parliament, as well as allowing her to implement whatever domestic policies she chooses.
He said: "I think a lot of Ukip voters probably voted Conservative and I would urge them to think very carefully about what they are voting for". Nationalist party Plaid Cymru gained 33 seats for a total of 202 with control of one council. Ukip results resemble a auto crash.
Among the authorities which had declared their final results, Labour had control of nine councils and had lost control of seven. The party now has 385 fewer council positions compared to past year, and Jeremy Corbyn is being widely blamed for poor leadership and "unelectable" policies.
While it may be wrong to assume that the general election vote will mirror the patterns that have emerged today, Ukip's numbers in some general election voter intention polls have been dropping lately too.
Mr Corbyn told supporters in Leicester that the General Election was "a great opportunity.to create a society in which people are no longer held back by a system that is rigged for the rich". I am disappointed at every Labour defeat in the local elections. Nuttall put the poor results down to May talking tough on Brexit. Boundaries are often different between local and national elections - and to confuse matters further, the county council boundaries have been redrawn entirely since 2013.
In Abingdon North there was more good news for the party as Emily Smith took the seat from Conservative Sandy Lovatt.
"We have got what we wanted, but unfortunately we have been in a sense the victims of our own success", she told Sky News.
The SNP secured significantly less than 40 per cent of the local election "first preference" vote - that's more than 10 per cent less than achieved in 2015.
The shadow chancellor John McDonnell will say the rise to fund public services will affect only five per cent of earners and the majority on low and middle incomes will be protected by a "personal tax guarantee".
He insisted that Labour's vote had "held up" in areas of Wales where Corbyn had campaigned, and that there were signs that voters were developing more confidence in the party leader as he had the chance to get his message across.
