Zac Goldsmith is facing an investigation by Parliament’s sleaze watchdog over claims he delayed revealing thousands of pounds worth of donations from his rich friends, The Independent reports today.

The allegation is that the Tory candidate for Mayor of London omitted to declare donations of over £120,000 from the Register of Members Interests.

The claims were made by Labour MP Neil Coyle, who said:

It appears that Goldsmith has failed to correctly declare well over £120,000 of donations with some not registered with Parliament for over four years. These donations might be considered small change by Goldsmith, but there shouldn’t be one rule for the former non-dom and another for everyone else.

Goldsmith has been investigated before by the Electoral Commission over exceeding spending limits during election campaigns and I believe a full investigation into these new revelations is required to get to the bottom of what looks like major breaches of Parliamentary rules.

The revelations will come as an embarrassment to Goldsmith’s hapless campaign, which could only say:

We will be complying with the Standards Commissioner in due course.

Meanwhile, launching his manifesto today Zac Goldsmith will finally admit what he has been avoiding saying so far: he will push up transport fares in London even further.

Labour’s Sadiq Khan wasted no time jumping on the revelations

Let’s see how Goldsmith gets out of this one.
