Prime minister says conversation with US president on Thursday night focused on need for ‘practical plan’ to open strait of Hormuz

Tony Blair, the former Labour prime minister, has joined those saying the government should allow drilling for oil and gas in the Rosebank and Jackdaw fields in the North Sea.

Both applications were approved by the last Conservative government, but then overturned by a court ruling. Ed Miliband, the energy secretary, has to make a decision about the revised applications operating in a quasi-judicial capacity, which means he has to follow due process and can’t take the decision purely on political ground.

The current debate [on energy policy] is deadlocked between two incomplete responses. The government argues the answer is to accelerate Clean Power 2030, focusing on decarbonising the electricity system as quickly as possible. The opposition argues that the answer is to expand domestic oil and gas production. Both positions contain elements of truth, but neither addresses the core strategic problem: outside the power sector the UK economy remains overwhelmingly dependent on fossil fuels, and electricity is still too expensive to support mass electrification.

The UK is caught in a self-reinforcing high-cost, low-electrification trap. High electricity costs suppress demand, slowing the uptake of electric vehicles, heat pumps and industrial electrification. Weak demand growth, in turn, means that the fixed costs of the system – from networks to long-term contracts – are spread across a smaller base, keeping prices high. The result is a system that is too expensive to electrify and therefore remains dependent on fossil fuels and exposed to global shocks …

The first of these vital measures will ban anyone from possessing or publishing harmful pornography that shows incest between family members, and sex between step or foster relations where one person is pretending to be under 18.

A further amendment will criminalise the publication and possession of pornography where an adult is roleplaying as a child.

This government is uncompromising in our mission to protect women and girls online, and we have taken action to stop tech firms from publishing this abusive content.

In February, we told platforms that they must remove reported non-consensual intimate images within 48 hours.

I greatly welcome the government’s plans to fully address harmful pornographic content such as incest, step-incest and the mimicking of child sexual abuse. This content that is freely and widely available online is deeply harmful, normalising child sexual abuse and abusive relationships within families …

Today the government has answered our calls for change, and I am delighted that once again the UK is leading the way on regulating this high harm industry.
