Allies of Boris Johnson last night told him to sort out the ‘shambles’ in No 10 as backbenchers warned his authority has been ‘truly shattered’.

After the botched Owen Paterson scandal handling, Senior Conservatives asked the Prime Minister to overhaul his entire top-ranking team.

Lord Moylan, an adviser to Mr Johnson during his time as London mayor, said the Prime Minister was being ‘let down badly’ by both his ministers and inner circle in Downing Street.

‘There’s no escaping the fact that the No 10 operation is a shambles, worst for decades,’ said the Tory peer.

‘It needs a thorough clear out, with new people who both share the PM’s ambitions for the UK and can think out consequences of what they do.’

He added: ‘As for the Cabinet, there are lots of capable people at different levels in the Government but we don’t see them and instead continue with a Cabinet that, at best, fails to inspire and, at worst, fails to deliver.

‘Boris Johnson deserves better. [It is] not too late for him to act on this.’

As Tory MPs protested at having to vote to dismantle the Commons disciplinary process to prevent Mr Paterson being suspended for 30 day, the warning was issued. The Government then made a stunning U-turn that night.

Backbenchers stated that it was impossible for party whips not to claim their authority in the future when difficult votes are occurring.

‘The power of a three line whip is well and truly shattered,’ one said. ‘There is a huge disconnect between the Downing Street team and the parliamentary party.’

Another said the ‘knives are out’ for Chief Whip Mark Spencer and Commons Leader Jacob Rees-Mogg, who are blamed for the disastrous strategy.

Cabinet minister Nadhim Zahawi yesterday conceded the Government made ‘a mistake’ in its attempt to protect Mr Paterson.

It should not be combined with an overall overhaul of the Commons standards system, according to Education Secretary.

‘The Prime Minister has always been very clear that paid lobbying is not allowed,’ he told Sky News. ‘The mistake is the conflation of creating a fairer system with the right of appeal for Parliamentarians to be able to put forward an appeal process.

‘Conflating that with the particular case of Owen Paterson was a mistake… upon reflection yes it was a mistake.’

Sir David Lidington, former leader of the House of Commons, said the row had damaged politicians’ reputations.

‘Clearly there was a pretty appalling set of misjudgments involved,’ he told BBC Radio 4’s Today programme.

‘The reputation of the House of Commons as an institution and MPs of all parties will have been damaged by the events of the last 24 hours.’

The former Conservative MP also said the affair has ‘weakened the Government’, making it harder for Mr Johnson to win support from backbench MPs on potentially unpopular measures in future.

‘If you ask your troops to march through the lobby on something like this – which they don’t think is right – and then you U-turn on it, it’s going to be more difficult next time around,’ he said.

Lord Barwell, who was Theresa May’s chief-of-staff, said the decision to whip MPs to vote for Mr Paterson to be spared punishment was a ‘terrible mistake’.

He told LBC Radio: ‘The Prime Minister… will have significantly dented his reputation with Conservative MPs who will be livid that they were whipped to vote for something, took a huge amount of flak understandably from their constituents, and then saw a U-turn in less than 24 hours.

‘It remains to be seen how much damage is done to the standing of the Conservative Party with the general public.’

Chris Bryant (Labour chairman of the Commons standard committee) last night called for Mr Rees Mogg’s resignation.

‘I personally think the Leader of the House’s position has become untenable. He has created a crisis for Parliament by standing out and talking for 45 minutes in favour of a motion that was the direct, polar opposite of the rule of law,’ Mr Bryant told the i paper.

He also revealed that Kathryn Stone, the independent standards commissioner, has been given additional security as a result of an ‘orchestrated smear campaign’ against her.
