Brexit giveth, and Brexit taketh away. The Conservatives have won a thumping victory in the Sleaford and North Hykeham by-election. The numbers that matter:

Caroline Johnson (Conservative) 53.5%

Victoria Ayling (Ukip) 13.5%

Ross Pepper (Liberal Democrat) 11%

Jim Clarke (Labour) 10.2%

It's one of the Tory party's best by-election performances while in government - their vote share still above 50 per cent and miles ahead of their nearest competitors. What will make the victory even sweeter is what's happened to the Labour vote - a seven point fall in their share of the vote, and a collapse from second place to fourth.

But for all the hype around Paul Nuttall and how he was set to transform Ukip into a Labour-killer, that party's vote share is down too - it's only the collapse in Labour's vote that has allowed them to take second, rather than any great uptick in that party's fortunes.

The only party with anything to cheer about - other than the Conservatives - are the Liberal Democrats, continuing their post-referendum pattern of astonishing revival. What many seem to have misunderstood: even in places like Hykeham, which backed Brexit by a heavy margin, the Remain vote is significantly larger than the Liberal one. If they can hold onto to their 2015 vote and add Remain votes from Tory and Labour, they can hope for real gains at the next election. (Of particular significance - in the South West, the Labour and Green vote they need to take back seats from the Conservatives, tends to have voted Remain on 23 June.)

What's increasingly clear: the further anti-immigration turn of Theresa May's government has fixed the Conservatives' Ukip problem, but they've acquired a Liberal Democrat one. Labour, meanwhile, hasn't fixed its Ukip problem and now as a Liberal Democrat one to match.

Blairites used to worry that Ed Miliband was pursuing a 35 per cent strategy (the Labour vote in 2010 topped up with disgruntled Liberal Democrats). It's fairly clear that Theresa May has decided to pitch her tent towards the 52 per cent who voted Leave, while Tim Farron is going for the 48 per cent who decided to Remain. What Labour wants is to talk about their plans to fix the British economy and negotiate a better Brexit than the Conservatives can. That has the advantage of not putting further pressure on the splits in the parliamentary Labour party and the divide in the party's electoral coalition. The real risk, however, is what they've ended up with is a zero per cent strategy.

Downing Street has disavowed remarks made by Boris Johnson, this time about the Middle East. The Foreign Secretary said Saudi Arabia was "twisting and abusing" Islam and acting as a "puppeteer" in the region. It's a further rift between Downing Street and the FCO. "Saudi row wides Boris rift with May" is the Telegraph's splash.
