Baron
It should be noted also that:
In Scotland, a Baron is called a Lord of Parliament
There are five categories of British peerage and they have a hierarchy themselves:
1. Peerage of England
2. Peerage of Scotland
3. Peerage of Ireland
4. Peerage of Great Britain
5. Peerage of United Kingdom
Also peerages are ranked based on creation date.
Therefore a Baron of the United Kingdom is a lower grade than a Baron of England, and the lower of two Baronies of the United Kingdom would be the one created most recently.
Hope that edit helps!

I believe the highest rank (not the oldest) is the title of Duke.
A Duke is the highest rank in the British Peerage. See the related question link below.
From highest rank to lowest rank: # Duke # Marquess # Earl # Viscount # Baron The are ranks of Gentry that include Knight and Baronet, but they are not considered "Peerage", therefore, not nobility under British law.
The Baron is the lowest male in the British peerage.
There are no Counts in the peerage, this being a continental European title. The British equivalent is Earl, ranking below Marquess and above Viscount. The wife of an Earl is known as a Countess though, just to confuse matters!
traditionally a Duke is ranked just below a king or queen, it is the highest peerage in the UK, that's why prince phillip is a Duke
Victoria Cross (VC)

I think it is The First Lord Seaman.
Baron Mowbray
Lieutenant General (OF-9) As Field Marshal is the highest rank, General must be the second highest and Lt-Gen the third.
The highest rank attainable in the British Army is that of Field Marshal. There are currently seven living Field Marshals, the most senior is Baron Richard Vincent of Coleshill of the Royal Artillery.
A member of the highest rank of nobility in Germany and Austria, corresponding to the British duke.
