The Conservative Party will launch its general election manifesto later, promising to bring back the Withdrawal Agreement Bill before Christmas to achieve Brexit by the end of January.
Boris Johnson will unveil the document in the West Midlands later.
It will include a headline promise to “get Brexit done” alongside plans for a “triple tax lock” and a pledge to raise the National Insurance threshold.
Mr Johnson has vowed to “unleash the potential” of the UK.
The manifesto includes a promise not to raise income tax, national insurance contributions or VAT.
